When you use a slingshot to fire a rock you stretch the rubber band storing potential energy. You stretched the rubber band so that it had 100-J of potential
energy. When you calculated the kinetic energy, you calculated the rock to only have 90-J of energy. What happened to the other 10-J?
A. It was lost in flight
B. It was transformed to sound and thermal energy
C. The calculations are wrong
