A98-kg fullback, running at 5.0 m/s, attempts to dive directly across the goal line for a touchdown. just as he reaches the line, he is met head-on in midair by two 68-kg linebackers both moving in the direction opposite the fullback. one is moving at 2.0 m/s, the other at 4.0 m/s. they all become entangled as one mass.
(a) sketch the event, identifying "before" and "after" situations. (do this on paper. your instructor may ask you to turn in this work.) this answer has not been graded yet.
(b) what is the velocity of the football players after the collision? (take the positive direction to be the initial direction of the fullback.) m/s
(c) does the fullback score a touchdown?
yes
no
