A block of wood is placed on a frictionless horizontal surface and a 7.00 g bullet is fired from a gun into the 1.00-kg block of wood and remains embedded. The bullet has an initial speed of 500 m/s. Find the speed of the block and bullet after the collision. Find the impilse delivered to the block by the bullet. If the collision time is 2 x 10^-4 s, what is the average force exerted by the block on the bullet.
