Question

A bowling ball of mass m kg is rolled on a smooth surface at a speed of vms. The ball moves at this speed and stresa spring system attached to a vertical rigid wall, as shown in figure (0) Lm figure 1) smooth floor wall Lm ball stopped smooth floor figure (1) The spring compresses from its original length of L, to its minimum length of Las the ball comes to rest, as shown in figure 1). What is the spring constant? Assume there is no effect of air resistance and friction. A mg Lori B. m(L-1) с ти? (Lo-L? 0. mv Lo-L MACBOOK PICS
