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)

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...
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
A 120-kg tackler moving at 2.7 m/s meets head-on (and tackles) an 87-kg halfback moving at 6.9 m/s . 1) What will be their mutual speed immediately after the collision?
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 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 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...
A 135-kg rugby player running east with a speed of 4.00 m/s tackles a 92.5-kg opponent running north with a speed of 4.4 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.) I got the answer to part A: (a) What is the velocity of the players immediately after the tackle? magnitude 2.97 m/s direction 37 degrees counterclockwise from the +x-axis I don't understand how...
A 76.7 kg linebacker (X) is running at 6.83 m/s directly toward the sideline of a football field. He tackles a 87.8 kg running back (O) moving at 9.49 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 o relative to the sideline, as shown in the diagrams. Before impact After impact What is the common speed...
1. Two football players crash into each other. The linebacker is 100 kg. Just before collision occurs, his velocity is 4 m/s. During the collision, the linebacker exerts a force of 100 N against the wide receiver. What is the magnitude of force that wide receiver exerts on the linebacker?
