The acceleration due to gravity near the surface of the mars is about one-third of the value near the earth's surface. if a rock fell for the same amount of time on mars and earth, the speed with which the rock hit the ground on mars would be.


Expert Answer

Step 1

To determine: The speed of the rock when it hits the ground on Mars.

Given Information: The gravitational acceleration on Mars is one-third of the gravitational acceleration on Earth. The time of free fall of the rock is same both on Earth and Mars.

Step 2

Write the kinematic relation between initial and final velocity

Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time of free-fall.

Step 3

The initial velocity for free-fall is zero.

Using the above relation, write the kinematic relation between initial and final velocity on Earth...
