A man is 48m behind a bus which is at rest. The bus starts accelerating at the rate of 1m//s^(2) , at the same time the man starts running with uniform velocity of 10 m/s. What is the minimum time in which the man catches the bus ?

Two bodies start moving in the same straight line at the same instant of time from the same origin. The first body moves with a constant velocity of 40 m/s, and the second starts from rest with a constant acceleration of 4 "m/s"^2 . Find the time that elapses before the second catches the first body. Find also the greatest distance between then prior to it and the time at which this occurs.
