1. work = force * distance = 24 N * 1.5 m = ? Joules
... what box?
2. momentum is conserved
v * .005 = 10 * .505
1. As you and your bandmates prepare to rehearse, you push on your drum set to slide it into position. You exert a force of F = 24 N, kinetic friction opposes the motion with a force of Ff = 22 N, and you slide the drums a distance of d = 1.5 m. What is the net work done on the drums? What is the change in the box’s kinetic energy?
2. A 0.005 kg bullet hits a 0.5 kg block of stationary wood. If the bullet becomes lodged in the block and they fly off together with a velocity of 10.0 m/s, what was the original velocity of the bullet before the collision?
