A cart of mass 2.0 kg2.0\text{ kg}2.0 kg is at rest on a rough horizontal track. A small plasticine ball of mass 0.50 g0.50\text{ g}0.50 g travels horizontally towards the cart. The ball collides and sticks to the cart. After the collision, the cart with the embedded ball moves with an initial speed of 0.060 m/s0.060\text{ m/s}0.060 m/s.
Calculate the impulse exerted on the cart during the collision.
Calculate the speed of the ball just before it hits the cart.
As the cart moves along the rough track, it slows down and stops. Explain, in terms of work done, the energy changes that take place as the cart slows down.
