An archery bow is drawn a distance d = 0.29 m and loaded with an arrow of mass m = 0.094 kg. the bow acts as a spring with a spring constant of k = 112 n/m, and the arrow flies with negligible air resistance. to simplify your work, let the gravitational potential energy be zero at the initial height of the arrow. how fast will the arrow travel and it leave the bow?
