A motor car starting from rest travelled for 10 seconds with an uniform. acceleration of 5 m //s ^2 . What is the final velocity? Find the distance covered by the car.

Two objects, each of mass 1.5 kg, are moving in the same straight line but in opposite directions. The velocity of each object is 2.5 m s^-1 before the collision during which they stick together. What will be the velocity of the combined object after collision?

A body of mass 2kg moving with velocity 10 m/s collides another body of mass 500 g and moving with velocity 4 m/s. After collision if the 2nd body attains velocity of 8m/s, what will be the velocity of first body?

A block of mass 15 kg is placed on a long trolley. The coefficient of static friction between the block and the trolley is 0.18. The trolley accelerates from rest with 0.5 m s-^2 for 20 s and then moves with uniform velocity. Discuss the motion of the block as viewed by (a) a stationary observer on the ground, (b) an observer moving with the trolley.

A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 second from his initial position?
