A 73.3-kg linebacker ("X") is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7-kg running back ("O") moving at 8.61 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 φ relative to the sideline, as shown in the diagrams below. What is the common speed of the players, immediately after their impact? What is the angle, φ, of their motion, relative to the sideline?

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

On a very muddy football field, a 120 kg linebacker tackles a 75 kg halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.7 m/s north and the halfback is sliding with a velocity of 7.4 m/s east. A.) What is the magnitude of the velocity at which the two players move together immediately after the collision? B.) What is the direction of this velocity? (In degrees north of east)

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3.

need help with this two questions, please !!
Two ice skaters, Daniel (mass 60.0 kg) and Rebecca (mass 45.0 kg), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 13.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 7.00 m/s at an angle of 54.1" from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink. What is...
