A stone is thrown up with a velocity of 54 m/s from the ground. While coming down, it strikes a glass pan, held at half the height through which it has risen and loses half of its velocity in breaking the glass. Determine the time taken to reach the maximum height and the velocity with which it will strike the ground and total time taken to reach the ground

Question
A stone is thrown up with a velocity of 54 m/s from the ground. While coming down, it
strikes a glass pan, held at half the height through which it has risen and loses half of its
velocity in breaking the glass. Determine the time taken to reach the maximum height
and the velocity with which it will strike the ground and total time taken to reach the
ground
Solution
1. The time taken to reach maximum height in seconds is
2.The maximum height reached in m is
3.The distance between glass pan to the maximum height in m is
4.The velocity when the stone hits the glass pan in m/s is
5.The velocity of the stone when it hits the ground in m/s is
6.The total time taken by the stone in seconds is
