Starting from rest, a train traveIs a certain distance with a uniform acceleration alpha . Then it traveIs with a uniform retardation beta and finally comes to rest again. If the totaI time of motion is t,find (i) the maximum velocity attained and (ii) the totaI distance travelled by the train.

Starting from rest a body moves at first with constant acceleration a. Then it moves with a uniform velocity and finally comes to rest with a constant retardation a. If the displacement is s and time taken is t, prove that the body was in motion with uniform velocity for a time interval of sqrt(t^(2)-4s//a).

Starting from rest, a body moves in a straight line with a constant acceleration. Describe the nature of the graph relating the displacement with time.
