Two Children,A and B, fire identical 10g ball bearing from a catapult. The elastic band of each catapult is elastically extended by 0.10m and then released to fire a the ball bearings.
Child A's elastic band has a spring constant of 144 N/m. Calculate the energy transferred to the kinetic energy store of child A's ball bearing. Use an equation from the equation List.
Energy=...............................J

(1/2) k x^2 = (1/2)(144)(.01) Joules
The initial speed of child b's ball bearing is twice as fast as childs a's ball bearing calculate the spring constant of child b's elastic band. give answer to 2 significant figures
