An archer pulls her bow string back 0.400 m by exerting a force that increases uniformly from zero to 240 N.
(a) What is the equivalent spring constant of the bow?
(b) How much work does the archer do in pulling the bow?
(a) k = (Maximmum force)/(Maximum deflection)
(b) W = (1/2)(Maximum force)(Maximum deflection)
