A ball is dropped from the top of a high tower on a planet. In the last before hitting the ground, it covers a distance of . Acceleration due to gravity (in ) near the surface on that planet is
Step 1: Given data
A ball is dropped from a high tower.
Let the ball covers the distance of in sec.
And the ball covers the distance of in sec.
Initial velocity of a ball,
Step 2: Finding the acceleration due to gravity.
Here, use the equation of motion, for
For ,
Put the value of from equation first we get,
Therefore, the value of acceleration due to gravity near the surface of the planet is
