When an archer pulls an arrow back in his bow, he is storing potential energy in the stretched bow.

(a) Compute the potential energy stored in the bow, if the arrow of mass 4.95 10-2 kg leaves the bow with a speed of 38.0 m/s. Assume that mechanical energy is conserved?

(b) What average force must the archer exert in stretching the bow if he pulls the string back a distance of 30.0 cm?
