4) A ball with a mass of 0.15 kg has a velocity of 5 m/s. It strikes a wall perpendicularly and bounces off straight back with a velocity of 2 m/s. The ball underwent a change in momentum equal to (There is only one answer) (2p) A) 0.20 kg. m/s B) 1.20 kg. m/s C) 1.05 kg. m/s D) 6 kg. m/s E) 8.5 kg. m/s 5) A 2-kg mass moving with a velocity of 6 m/s collides elastically with...
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...
The figure above shows a portion of the trajectory of a ball traveling through the air. Arrows indicate its momentum at several locations. At these locations, the ball's momentum is: p^vector_B = < 3.13, 2.88, 0 > kg middot m/s p^vector_C = < 2.65 1.02, 0 > kg middot m/s p^vector_D = < 2.34 -0.52, 0 > kg middot m/s p^vector_E = < 2.07, -1.88, 0 > kg middot m/s (a) which of the diagrams below correctly shows the graphical...
A 0.12-kg ball is moving at 6 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 14 m/s. What is the magnitude of the change in the momentum of the ball? 0.39 kg middot m/s 0.42 kg middot m/s 1.3 kg middot m/s 2.4 kg middot m/s Alex throws a 0.15-kg rubber ball down onto the floor. The ball's speed just before impact is 6.5 m/s, and just after is 3.5...
