    Conservation of energy
    A track consists of an arc and a straight horizontal path. A 3kg block is released from rest at Point A. At Point B is has a velocity of 6.5 m/s. THen it collides and sticks to and identical block at rest and they slide into and compress a spring with a spring constant of 165 N/m. Ignore Friction between the block and the track surface. How far do the blocks compress the spring before coming to a stop?
