Question

a ball Falls from a height such that it strikes the floor of lift at 10 ms. if the lift is movin upward direction with 1ms . the t he velocity with which the ball rebounds after elastic collision​

Answer 1

Answer:

I don't know this answer

Explanation:

i hope you have been understand

Answer 2

Answer:

12m/s

Explanation:

Relative velocity of ball w.r.t lift =10+1=11m/s.

Collision is elastic therefore ball rebound with velocity relative to lift=11m/s.

But the velocity w.r.t ground=11+1=12m/s.
