Use the following information to answer parts a–b. The strings in a compound bow behave approximately like a spring. A bowstring is pulled back 0.60 m with a maximum force of 267 N (AKA a 60-pound draw weight) to shoot an 18 g arrow. Assume energy is conserved. a) At what speed would the arrow be launched? (Note: W = FΔd uses the average force while F = -kx uses the instantaneous force.) b) If the arrow were shot straight upward, how far would it rise? (This would be extremely dangerous, do not ever shoot an arrow upward.)

Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.
