A box with a mass of 5 kg is placed at the top of an inclined plane that is 10 meters long and makes an angle of 30o with the horizontal. The coefficient of kinetic friction between the box and the inclined plane is 0.2. The box is given a slight push and slides down the incline. Calculate the acceleration of the box as it slides down the inclined plane.

A cart with a mass of 25kg moves at a speed of 30m/s towards a cart with a mass of 35kg which is initially at rest. Upon collision, the carts stick together and move together after the collision. Calculate the velocity of the system after the collision.

An elastic collision is one in which
