A 78.5-kg linebacker ("X") is running at 7.19 m/s directly toward the sideline of a football field. He tackles a 96.9-kg runn8ing back ("O") moving at 9.27 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision both players momentarily leave the ground and go out-of-bounds at an angle phi relative to the sideline, as shown in the diagrams below.

A 100-kg football linebacker moving at 2.5 m/s tackles head-on an 80-kg halfback running 3.0 m/s. Neglecting the effects due to digging in of the cleats, (a) the halfback will drive the linebacker backward (b) neither player will drive the other backward (c) the linebacker will drive the halfback backward (d) this is a simple example of an elastic collision
