A 5 g bullet with speed of 400m/s gets stuck in a 1 kg wooden block (originally not moving). (a) Classify the collision. (b) Find the new speed of block+bullet. (c) Find the amount of kinetic energy lost. Where does it go? 2.Suppose, in the previous problem the bullet does not get stuck but emerges on the other side of the block with speed of 100m/s. Find the speed of the block
Old naval ships fired 14 cannon balls from a 240 cannon. It was very important to stop the recoil of the cannon, since otherwise heavy cannon would go careening across the deck of the ship.
