A particle starting from rest has a constant acceleration of `4 m//s^2` for 4 s. It then retards uniformly for next 8 s and comes to rest. Find during the motion of particle (a) average acceleration (b) average speed and (c) average velocity.

A particle starting from rest with constant acceleration travels a distance x in first 2s and a distance y in next 2s then

A particle starts from rest and accelerates constantly with 2m//s^(2) for 10 s and then retards uniformly with same rate till it comes to rest. Draw the x-t, v-t and a-t graphs.

A particle starts from rest and moves with a constant acceleration of 4 m//s^(2) for 10 s , then it moves under constant seceleration and stops in 20 s . Find (a) the maximum velocity attained by the particle (b) the total distance traveled and (c ) the distance/distances from the origin, when the particle is moving at half the maximum velocity.
