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. What is the concern speed of the players, immediately after...
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...

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. A 2000 kg SUV traveling at 7 m/s south runs into the rear end of an 800 kg compact car sitting...
A 190-kg rugby player running east with a speed of 4.00 m/s tackles a 99.0-kg opponent running north with a speed of 3.90 m/s. Assume the tackle is a perfectly inelastic collision. (Assume that the +x axis points towards the east and the +y axis points towards the north.) (a) What is the velocity of the players immediately after the tackle? magnitude m/s direction ° counterclockwise from the +x axis (b) What is the amount of mechanical energy lost during...
On a touchdown attempt, a 95.0 kg running back runs toward the end zone at 3.75 m/s. A 111-kg linebacker moving at 4.10 m/s meets the runner in a head-on collision. If the two players stick together. (a) What kind of collision is it and what quantity is conserved in this problem? (0.5 point) (b) Write down the appropriate conservation equation for the system. (0.5 points) (c) Find the final velocity vf. (both magnitude and direction) (0.5 points) (d) Calculate...
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...
Football Collision A 96 kg running back, moving at 5.29 m/s, runs into a 109 kg defender who is initially at rest. What is the speed of the players just after their perfectly inelastic collision? Incorrect. What is the change in their total kinetic energy due to this totally inelastic collision?
