V 53 A rubber-band slingshot shoots a 25 g stone. Ep F 2Fmaxx, 1 2 a. What is the initial speed of the stone if the rubber band is drawn back 0.15 m with a maxium force of 27 N? Remember that Ep = kx and, because F = kx, E, = (you will be using the average force which is obtained by dividing the maximum force by two. i.e. Ep= Fave*d  = = Fmax X
