1. A 0.03-lb bullet traveling at 1300 ft> s strikes the 10-lb wooden block and exits the other side at 50 ft> s as shown. Determine the speed of the block just after the bullet exits the block, and also determine how far the block slides before it stops. The coefficient of kinetic friction between the block and the surface is μk = 0.5.
2. A 0.03-lb bullet traveling at 1300 ft>s strikes the 10-lb wooden block and exits the other side at 50 ft>s as shown. Determine the speed of the block just after the bullet exits the block. Also, determine the average normal force on the block if the bullet passes through it in 1 ms, and the time the block slides before it stops. The coefficient of kinetic friction between the block and the surface is μk = 0.5.
