A crane of mass M = 11500 kg lifts a wrecking ball of mass m = 1310 kg directly upward.

a) Find the magnitude of the normal force exerted on the crane by the ground while the wrecking ball is moving upward at a constant speed of v = 1.45 m/s.

(in N)

b) Find the magnitude of the normal force if the wrecking ball's upward motion slows at a constant rate from its initial speed v = 1.45 m/s to a stop over a distance D = 0.247 m.
