The pole is the center of the circle. The total kinetic energy of the system after the elastic collision and the cord is broken, using (37-7) and (37-10) is 22 2 00 0 34 3 84 8 mv mv mv KK. The force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring for small distances. Calculate the elastic potential energy stored by the spring if it is extended by a distance of 0. . chat rbate
