Answer 1

Answer:

I am from Gujarat and uuu

Height from which the ball is dropped s=90m

Initial velocity of the ball, u=0

Let us consider that the final velocity of the ball is v

The time taken by the ball to reach the ground is given by:

s=ut+

t=

=4.29s

The final velocity of the ball as it reaches the ground is given by:

v=u+at

⇒v=0+9.8×4.29=42.04m/s

The ball losses it's one-tenth of the velocity at collision.

So, the rebound velocity of the ball,
