Mechanics And Wave Motion

We are given that the ball is projected vertically upward with speed from a height , and when it reaches the ground, its speed is . We need to find the time taken to reach the ground and the value of height . Using the equations of motion:
1. , where:
- (final velocity)
- (initial velocity)
- (height traveled)
So, , which simplifies to:
2. To find the time , we use the formula:
Solving for , we get:
