1.	A small sphere, dropped from a height of 10 cm, on striking the floor, reboundes and rises to a height of 15 cms Is this possible ? Explain your answer.
Answer» Solution :Here` e = sqrt (( h _(2))/( h _(1))) = sqrt ((15)/(10)) GT 1.`Since the maximum value of e is 1, it is not possible. This ALSO violates energy CONSERVATION law.
