The two bodies of 1.6 kg, A and B, collide. The velocities before the collision are vvecA = (12ihat + 25jhat) m/s and vvecB = (-10ihat + 5.0jhat) m/s. After the collision, vvec'A = (-2.0ihat + 16jhat) m/s.
Determine the final velocity of B?
Determine the change in the net kinetic energy (comprising sign)?
