Answer:

Tarzan will be moving at 7.4 m/s.

Explanation:

From the question given above, the following data were obtained:

Height (h) of cliff = 2.8 m

Initial velocity (u) = 0 m/s

Final velocity (v) =?

NOTE: Acceleration due to gravity (g) = 9.8 m/s²

Finally, we shall determine how fast (i.e final velocity) Tarzan will be moving at the bottom. This can be obtained as follow:

v² = u² + 2gh

v² = 0² + (2 × 9.8 × 2.8)

v² = 0 + 54.88

v² = 54.88

Take the square root of both side

v = √54.88

v = 7.4 m/s

Therefore, Tarzan will be moving at 7.4 m/s at the bottom.

Answer: find the answer in the explanation

Explanation:

Average velocity is the average value of magnitude of initial velocity and final velocity.

If U = initial velocity and V = final velocity, then average velocity can be expressed as

Average velocity = ( U + V )/2

A vehicle who takes 60 minutes to cover 30 miles north and then 30 miles south and end up at the same place, has an average speed of 60 miles divided by 60 minutes, or 1 mile per minute.

Instantaneous velocity is the distance covered in a specific direction per time taken. Instantaneous velocity can be expressed as

Velocity = displacement/ time.

Uniform velocity occurs when we have a constant velocity. That is, when velocity does not change. When a vehicle travels in equal distances in equal intervals of time.

how long would it take for a radio wave sent from a space satellite circling mars to reach Earth? Assume that radio waves (a for

kati45 [8]

Answer:

3 Minutes 2 seconds to 22 minutes 16 seconds

Explanation:

Lets assume the Mars to be at the closest distance to Earth. This distance (D) = 54.6 Million km

The signal travels at the speed of light, so speed of the signal (V) = 300000 km/s

So, the time (T) taken by the radio wave to reach Earth from Mars will be,

$T = \frac{D}{V}$

$T = \frac{54600000}{300000}$

Thus, T = 182 Sec = 3 Minutes 2 seconds.

The radio wave will take minimum 03 Minutes 02 seconds to reach Earth. Here is should be noted that the distance between the two planets keep on changing as they revolve around the Sun. There will come a point when Mars is farthest from Earth and the distance (D) will be 401 Million km. Then, the time will change to ,

$T = \frac{401000000}{300000}$

T = 1336.67 sec = 22.27 Minutes.

So the maximum time will be 22 minutes 16 seconds.
