Here's the question: 1. A ball with a mass of 0.675 kg was launched towards a wall. If it was pulled back a distance of 1.75 m in the slingshot using 3.50x10^2 N of force, what is the speed of the ball as it is released from the slingshot? 2. Ep(elas)=fxd?? that could possibly be divided by the mass to give you velocity 3.... I really have no idea and I really need help.
