Mechano, the evil robot ccat, has captured the mouse, Jerry (mJ=0.600 kg), and is about to launch him out of a window using his robotic sling shot.
The slingshot has two elastic bands that hold the pouch, which is wrapped around Jerry. Treat each of the bands like a Hooke's Law spring, with a spring constant of k=1850 N/m. The rest length of each "spring" is L0=4.00×10−2 m.
Answer the two questions below, using three sig figs.
Part A - Just befor the launch, the "springs" have a length of Lf=0.110 m. How much elastic potential energy, UE, is stored in each "spring?"
