- A 38g bullet is fired at a stationary bag which is hanging vertically from the ceiling. The speed of the bullet is 180m/s. If the mass of the bag is 5.0kg, what is the maximum height it will reach?

- A spring is compress 8.7cm between two carts of 1.0kg and 1.5kg respectively. If the spring constant is 89N/m what is the velocity of the heavier cart.

When a bullet ( of mass 'm') hits a Block ( of mass M) with a speed 'v' and get arrested in the block, the bullet and block system will start moving with a speed 'Vb'.

This speed can be calculated from the law of conservation of Momentum as
