Question

4. In the 200 film Remember the Titans, there is a scene in which the Titans, fed up with bad officiating, decide they will keep their opponent from gaining another yard. In their ensuing defensive effort, there are some serious hits. The opposing team’s quarterback (played by Andy Francis) runs the ball, and Julius Campbell (played by Wood Harris) meets him head-on. The quarterback has a mass of 76 ?? and runs at a speed of 7.3 ?⁄?. Julius, at linebacker, has a mass of 90 ?? and runs at a speed of 7.8 ?⁄? (remember, he gets a bit more of a running start).

1. Rather than just deliver a hit, Julius tackles the quarterback, wrapping up and going down

   with him (so that they “stick together”). Find the final speed of the two after the collision.

2. Who loses more energy in the collision?
