Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the drawstring back 70 cm from its rest position and holds it in position with a force of 160 N. If the mass of the arrow is 55 g and the "spring" is massless, what is the speed (in m/s) of the arrow immediately after it leaves the bow? 40 X m/s
