Two 1.6 kg bodies, A and B, collide. The velocities before the collision are vector vA = (18i hat + 35j hat) m/s and vector vB = (-10i hat + 10.0j hat) m/s. After the collision, vector v'A = (-2.0i hat + 22j hat) m/s.
(a) What is the final velocity of B?
(b) What is the change in the total kinetic energy (including sign)?
