1.	A ball of density d, is dropped on a solid horizontal plane . It returns intime t_1 to thepoint from where it was droppedafter an elastic collision . From the same height, the ball is now dropped on a liquid surface ofdensity d_L (i)if dlt d_L, the time required by the ball to return to the original height is t_2. Find the value of t_2 in terms of t_1 ,d and d_L.
Answer» ANSWER :`t_2=(d_L)/(d_L-d)t_1`
