A child throws a 6 kg package out horizontally with a speed of 10m/s. Calculate the velocity of the boat immediately after, assuming it was at rest initially. The mass of the child is 23 kg and the boat is 55 kg. Ignore water resistance.
A 13 g bullet traveling 220m/s penetrates a 2 kg block and emerges cleanly at 165m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges?
