Potential energy can be found simply with the force, so finding the spring constant can be slightly redundant which is why i used Ep=1/2Fx rather than Ep=1/2kx2 seeing as F=kx Therefore JazzFusion for A3: the potential energy is Ep=1/2(27N)(0.15m) Ep=2.025J So the elastic potential...

Homework Statement (A)A rubber band slingshot shoots a 25g stone What is the intial speed of a stone if the rubber band is drawn back 0.15m with a force of 27N? (B) How high will the stone rise if it is shot straight upward? m=0.025kg x=0.15m F=27N Homework Equations Ep=1/2Fx For...
