A glass marble dropped from a certain height above the horizontal surface reaches the surface in time t and then continues to bounce up and down. The time in which the marble finally comes to rest is

A ball is dropped from a certain height on a horizontal surface.It bounces up and down,finally comes to rest.If the time taken for first fall is 10s, then find the time taken to come to rest.(e=0.2)

A block of mass m_(1) lies on the top of fixed wedge as shown in fig. and another block of mass m_(2) lies on top of wedge which is free to move as shown in fig. At time t=0 both the blocks are released from rest from a vertical height h above the respective horizontal surface on which the wedge is placed as shown. There is no friction between block and wedge in both the figures. Let T_(1) and T_(2) be the time taken by the blocks respectively to just reach the horizontal surface. then
