A small steel ball bounces on a steel pl...

A small steel ball bounces on a steel plate held horizontally. On each bounce the speed of the ball arriving at the plate is reduced by a factor e (coefficient of restitution) in the rebound, so that `v_("upward")=eV_("downward.")` If the ball is initially dropped from a height of 0.4 m above the plate and if 10 seconds later the bouncing ceases, the value of e is

A

`sqrt((2)/(7))`

B

`(3)/(4)`

C

`(13)/(18)`

D

`(17)/(18)`

A ball is dropped from a highly raised platform at t=0 starting from rest. After 6 second another ball is thrown downwards from the same platform with a speed v. The two balls meet at t=18 s. What is the value of v? (Take g=10 m/s^2 )

From the terrace of building of height H, you dropped a ball of mass m. It reached the ground with speed v. Is the relation mgH = frac(1)(2)mv^2 applicable exactly ? If not, how can you account for the difference ? Will the ball bounce to the same height from where it was dropped?
