Q. A 0.200 kg projectile is fired with a velocity of +745m/s at a 2.0kg wooden block that rests on a frictionless table. The velocity of the block, immediately after the projectile passes through it, is +45 m/s. Find out the velocity with which the projectile exits from block.

Q. In a playground, a wooden horse is attached to the ground by a stiff spring. When a 30 kg child sits on the horse, spring compresses by 17.00 cm. With the child sitting on the horse, the spring oscillates up and down with a frequency of 0.88 Hz. What is the oscillation frequency of the spring when no one is sitting on horse?
