A slingshot will shoot a 64-g pebble at a speed of 8.6 m/s. If the rubber bands have a force constant of 4.7 N/m, then how far were the rubber bands stretched? Express your answer to 1decimal place. I have done the equations and got my stretch but I am not able to get the original length of the rubber band.
