The world has ended. Zombies wander the land. You design a car with spikes on the front to try to drive through zombies in your way. Your 1,200 kg vehicle is driving at 40 m/s and
collides with a 100 kg zombie (it's a big onel) that is stationary, and the zombie sticks to your
spiked front end. How fast will you and the zombie be moving after the collision?
