2. Justin draws his compound bow and shoots an arrow. The 23g arrow leaves the bow with a velocity of 88 m/s. The power stroke of the bow is 57 cm; that is, the bowstring exerts force on the arrow through a displacement of 57 cm. The peak draw weight of the bow is 312 N. (This is the maximum force that the archer has to exert on the bowstring.) (Show all work) a. How much kinetic energy does the arrow have after release? b. How much work does the bowstring do on the arrow? c. What average force does the bowstring exert on the arrow?
