One 105 kg football lineman is running to the right at 2.65 m/s while another 125 kg lineman is running directly toward him at 2.70 m/s . Part A) What is the magnitude of the net momentum of these two athletes? Part B) What is the direction of the net momentum of these two athletes? Part C) What is their total kinetic energy?

A 10 kg penguin with an initial velocity of 6.0 m/s toward the
east runs onto a large area of level, frictionless ice. As the
penguin slides across the ice, it is pushed by the wind with a
force that is constant in magnitude and direction. The figure shows
the position of the penguin, at 1.0 s intervals, as it slides on
the ice; the positive direction of the x axis is toward
the east. The penguin first makes contact...

Two vehicles are approaching an intersection. One is a 2600 kg pickup traveling at 16.0 m/s from east to west (the −x- direction), and the other is a 1600 kg sedan going from south to north (the +y− direction at 23.0 m/s ). a. Find the x -component of the net momentum of this system. b. Find the y-component of the net momentum of this system. c. What is the magnitude of the net momentum? d. What is the direction...

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.

Two vehicles are approaching an intersection. One is a 2400 kg pickup traveling at 13.0 m/s from east to west (the −x- direction), and the other is a 1300 kg sedan going from south to north (the +y− direction at 21.0 m/s ). Part A Find the x -component of the net momentum of this system. Part B Find the y-component of the net momentum of this system. Part C What is the magnitude of the net momentum? Part D...

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...

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 racquet ball with mass m = 0.244 kg is moving toward the wall at v = 15 m/s and at an angle of θ = 27° with respect to the horizontal. The ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. The ball is in contact with the wall for t = 0.067 s. 1)What is the magnitude of the change in momentum of the racquet...
