15.7 kg toy is thrown by an angry child at a speed of 1.96 m/s. At the same time, another angry child hurls her toy of mass 11.8 kg back toward the other child so that it is moving with a velocity of -2.36 m/s directly toward the toy the first child threw. Assuming the toys collide in a perfectly inelastic collision, how fast are the toys moving after the collision? A) 0.06 m/s B) 0.26 m/s C) -1.01 m/s D) 0.11 m/s E) -0.51 m/s
