A man in a lift ascending with an upward acceleration `a` throws a ball vertically upwards with a velocity `v` with respect to himself and catches it after `t_1` seconds. After wards when the lift is descending with the same acceleration `a` acting downwards the man again throws the ball vertically upwards with the same velocity with respect to him and catches it after `t_2` seconds?
