How much is the velocity of a body when it travels 600m in 5 minutes?( with the full process)​

Answers

Answer 1
Its average speed, pretending that it traveled at a constant speed, is

v = s / t

= 600 m

5 x 60 s

= 2 m/s

but to be a velocity it needs a direction as well as a speed.

( Sorry. Can’t find a division line to put between the 600 m and the 5 x 60 s )

A lever of length 1m has been used to lift a load of 600N by applying an effort of 200N. If load is at 20cm from fulcrum, calculate mechanical advantages, velocity ratio and efficiency

solve numerical problem ​

Answers

Answer:

1) The Mechanical Advantage of the lever is 3

2) The velocity ratio of the lever is 4

3) The efficiency of the lever is 75%

Explanation:

A lever is a simple machine that is used to lift a heavy load with a little effort or force

The mechanical advantage is the ratio of the force output to the force input

The given parameters of the lever are;

The length of the lever = 1 m

The weight of the load (force output), [tex]F_r[/tex] = 600 N

The effort applied (force input), [tex]F_e[/tex] = 200 N

1) The Mechanical Advantage, MA of the lever is given as follows;

[tex]MA = \dfrac{F_r}{F_e} = \dfrac{600 \ N}{200 \ N} = 3[/tex]

The Mechanical Advantage, MA of the lever = 3

2) The velocity ratio, V.R., is the ratio of the distance moved by the effort, [tex]L_e[/tex], to the distance moved by the load, [tex]L_r[/tex]

For the lever, we have;

The distance of the load from the fulcrum, [tex]L_r[/tex] = 20 cm = 0.2 m

Therefore, we have;

The distance of the effort from the fulcrum, [tex]L_e[/tex] = 1 m - 0.2 m = 0.8 m

From which we have;

[tex]V.R.= \dfrac{L_e}{L_r} = \dfrac{0.8 \ m}{0.2 \ m} = 4[/tex]

The velocity ratio of the lever = 4

3) The efficiency, η, is given as follow;

[tex]\%Efficiency, \, \eta = \dfrac{M.A.}{V.R.} \times 100 = \dfrac{3}{4} \times 100 = 75\%[/tex]

The efficiency of the lever is 0.75 or 75%.

Explanation:

The length of the lever = 1 m

Therefore, we have;

The distance of the effort from the fulcrum, L_eL

"electromagnetic spectrum depends on wavelength and frequency"

When electromagnetic radiation interacts with single atoms and molecule,its behavior also depends on the amount of energy per quantum(photon)it carries wave number =1/wavelength in cm speed of light=wavelength x frequency energy = Planck's constant x frequency.

Electromagnetic radiation interacts with matter in different parts of the spectrum.

Electromagnetic radiation interacts with matter in different ways in different parts of the spectrum.The types of interaction can be so different that it seems justified to refer to different types of radiation.There is a continuum containing all these different kind of electromagnetic radiation.Thus we refer to spectrum but divide it up based on the different interaction with matter.

A car accelerates uniformly from rest and

diameter of a tire is 47.8 cm.
Find the number of revolutions the tire
makes during this motion, assuming no slip-
ping
Answer in units of rev.

Answers

Answer:

29.75 revolutions

Explanation:

The kinematic formula for distance, given a uniform acceleration a and an initial velocity v₀, is

[tex]d=v_0t+\frac{1}{2}at^2[/tex]

This car is starting from rest, so v₀ = 0 m/s. Additionally, we have a = 9.2/9.7 m/s² and t = 9.7 s. Plugging these values into our equation:

[tex]d=0t+\frac{1}{2}\left(\frac{9.2}{9.7}\right)(9.7)^2\\d=\frac{1}{2}(9.2)(9.7)\\d=4.6(9.7)\\d=44.62[/tex]

So, the car has travelled 44.62 m in 9.7 seconds - we want to know how many of the tire's circumferences fit into that distance, so we'll first have to calculate that circumference. The formula for the circumference of a circle given its diameter is [tex]c=\pi{d}[/tex], which in this case is 47.8π cm, or, using π ≈ 3.14, 47.8(3.14) = 150.092 cm.

Before we divide the distance travelled by the circumference, we need to make sure we're using the same units. 1 m = 100 cm, so 105.092 cm ≈ 1.5 m. Dividing 44.62 m by this value, we find the number of revs is

[tex]44.62/1.5\approx29.75[/tex] revolutions

A helicopter is moving past some clouds at a velocity of 5 km/hr north relative to the clouds. The clouds are moving past the ground at a velocity of 3.5 km/hr north. How fast is the helicopter going past the ground?

Answers

Answer:

8.5 km/hr

Explanation:

The helicopter is going past the ground at a velocity 8.5 km/hr in north direction relative to ground.

What is velocity?

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

Given that:

Velocity of a helicopter with respect to the clouds is: v= 5 km/hr in north direction.

Velocity of the clouds with respect to the ground: u= 3.5 km/hr  in north direction.

So, Velocity of a helicopter with respect to the ground: V = v + u

= ( 5 +3.5) km/hr in north direction.

= 8.5 km/hr in north direction.

Hence, the helicopter is going past the ground at a velocity 8.5 km/hr in north direction relative to ground.

A food package is dropped from a helicopter flying horizontally at a height of 125m. If the magnitude of the velocity of the packageafter 2seconds is 25m/s. Find

a. The speed of the helicopter at the moment the package is dropped.

b. The position of the package after 2s.

c. The time of flight of the food package

d. The horizontal distance covered.​

Answers

Answer:

a. The speed of the helicopter at the moment the package is dropped is approximately 15.519 m/s

b. The position of the package 2s after it is dropped is (31.038 m, -9.8 m)

c. The time of flight of the food package is approximately 5.105 seconds

d. The horizontal distance covered is approximately 79.22 m

Explanation:

The given parameters are;

The height at which the helicopter is flying = 125 m

The magnitude of the velocity of the package after 2 seconds, v = 25 m/s

a. The vertical velocity of the package, [tex]v_y[/tex], is given as follows;

[tex]v_y[/tex] = [tex]u_y[/tex] + g·t

Where;

[tex]u_y[/tex] = 0 m/s for the dropped food package

t = The duration of the package in the air = 2 s

g = The acceleration due to gravity = 9.8 m/s²

Therefore;

[tex]v_y[/tex] = g·t = 9.8 m/s² × 2 s = 19.6 m/s

We have,  [tex]v = \sqrt{v_x^2 + v_y^2}[/tex],

Where;

vₓ = The horizontal velocity of the food package = The horizontal speed of the helicopter

therefore, [tex]v_x = \sqrt{v^2 - v_y^2}[/tex], which gives;

[tex]v_x = \sqrt{v^2 - v_y^2} = \sqrt{25^2 - 19.6^2} \approx 15.519 \ m/s[/tex]

The speed of the helicopter at the moment the package is dropped ≈ 15.519 m/s

b. The vertical if the package after 2 s is given as follows;

The vertical position of the package after 2 s is given by the kinematic equation, h = 1/2·g·t² = 1/2 × 9.8 m/s² × 2 s = 9.8 m

The food package is located 9.8 m vertically below the point where it is dropped

The horizontal position, x, of the package after 2 s is given by the following kinematic equation, x = vₓ × t

Therefore, x = 15.519 m/s × 2 s ≈ 31.038 m

The coordinates of the location of the package 2 seconds after it is dropped is (31.038 m, 9.8 m)

c. The time of flight, [tex]t_{tot}[/tex], of the food package which is the time it takes the package to reach the ground from 125 m, is given as follows;

[tex]t_{tot} = \sqrt{\dfrac{2 \cdot h}{g} } = \sqrt{\dfrac{2 \times 125 \ m}{9.8 \ m/s^2} } \approx 5.051 \ seconds[/tex]

The time of flight of the food package, [tex]t_{125}[/tex] ≈ 5.105 seconds

d. The horizontal distance covered, [tex]x_{tot}[/tex] = vₓ × [tex]t_{tot}[/tex] ≈ 15.519 m/s × 5.105 s = 79.224495 m ≈ 79.22 m.
