A 99-kg fullback, running at 8.2 m/s, collides in midair with a 126-kg defensive tackle moving in the opposite direction. Both players end up with zero speed.
(a) Identify the "before" and "after" situations and draw a diagram of both. (Do this on paper. Your instructor may ask you to turn in this diagram.)
(b) What was the fullback's momentum before the collision?
kg · m/s
(c) What was the change in the fullback's momentum?
kg · m/s
(d) What was the change in the defensive tackle's momentum?
kg · m/s
(e) What was the defensive tackle's original momentum?
kg · m/s
(f) How fast was the defensive tackle moving originally?
