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 2100 kg truck is traveling east through an intersection at 2.0m/s when it is struck simultaneously from the side and the rear. One car is a 1200 kg compact traveling north at 5.0m/s. The other is a 1500 kg midsize traveling east at 10m/s. The three vehicles become entangled and slide as one body. What is the speed and the direction just after the collision?

A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. Assume that any other unbalanced forces are negligible. a. What is the speed of the wreckage just after the collision? b. In what direction does the wreckage move just after the collision? c. How much kinetic energy is lost in this collision.

Ann, running with a speed of 4.00 m/s along a straight track, passes Beth who is stationary. Ann continues to run with the same speed for another 600 m. As soon as Ann passes her, Beth starts running with a constant acceleration of 0.045 m/s2. (a) When Ann is at the 600 m mark, where is Beth? (b) How fast is Beth running at that time? At this time, Ann starts accelerating with a constant acceleration. She continues to accelerate...

A 30.0-kg mass is traveling to the right with a speed of 2.20 m/s on a smooth horizontal surface when it collides with and sticks to a second 30.0-kg mass that is initially at rest but is attached to a light spring with force constant 190 N/m. The other end of the spring is fixed to a wall to the right of the second mass. A. Find the frequency of the subsequent oscillations. B. Find the amplitude of the subsequent...
At the center of a 50-m-diameter circular ice rink, a 79 kg skater traveling north at 2.4 m/s collides with and holds onto a 62 kg skater who had been heading west at 3.9 m/s
At the center of a 50-m-diameter circular ice rink, a 79 kg skater traveling north at 2.4 m/s collides with and holds onto a 62 kg skater who had been heading west at 3.9 m/s. Part A How long will it take them to glide to the edge of the rink? Part B Where will they reach it? Give your answer as an angle north of west.
