Does a man standing at rest on a moving truck possess KE?

Does a man sitting in a moving train posses KE?

A truck starts from origin, accelerating with a m s^-2 in positive x - axis direction. After 2 s , a man standing at the starting point of the truck projected a ball at an angle 30^@ with velocity v m s^-1 . Find the relation between a and v such that the ball hits the truck. (Assume that truck is moving on horizontal plane and the man projected the ball from the same horizontal level of truck).

A person standing on a moving truck, throws a stone vertically up relative to himself. To a person, standing on the ground, the stone appears to : (immediately after being thrown).

A truck of mass 10 metric ton runs at 3ms^(-1) along a level track and collides with a loaded truck of mass 20 metric ton, standing at rest. If the trucks couple together , the common speed after the collision is

The figure shows a man of mass m standing at the end A of a trolley of maas M placed at rest on a smooth horizontal surface. The man starts moving towards the end B with a velocity u_(rel) with respect to the trolley. The length of the trolley is L. When the man starts moving, then the velocity of the trolley v_(2) with respect to ground will be:

A man of weight W is standing on a lift which is moving up words with an acceleration 'a' . The apparent weight of the man is
