A car of mass m1 = 2000.0 kg is moving at speed v1i = 20.0m/s towards East. A truck
of mass m2 = 5000.0 kg is moving at speed v2i = 10.0m/s towards North. They collide at an
intersection and get entangled (complete inelastic collision).
1. What is the magnitude and direction of the final velocity of the entangled automobiles?
2. How much kinetic energy is lost in the collision. That is, calculate the change in the
kinetic energy of the system.
