Find the speed and direction of the cue ball immediately after the collision. Assume that the balls have equal mass . 3.05 m/s, 346.56 o 4) A red ball traveling at 4m/s at an angle of 20° above horizontal collides elastically with a green ball, with twice the mass of the red ball, traveling at 3m/s at an angle of 35° below horizontal. After the collision, the red ball is traveling at angle of 10° below horizontal and the green ball is traveling at an angle of 5° above the horizontal. Assume both balls are traveling in the positive x direction the whole time. What is the final velocity of each ball? 1) A 1,000kg car is traveling east at 20m/s when it perfectly inelestically collides with a northbound 2,000kg car traveling at 15m/s. If the coefficient of kinetic friction is 0.9, a) How far do the two cars skid before coming to a stop? 8.19m b) What angle do they travel at? 56.3º c) Is kinetic energy conserved during this collision? 2) A 400kg bumper car starts from rest and accelerates at 2.5m/s 2 to the right over a distance of 20m when it collides perfectly elastically with a 600kg bumper car traveling at 5 m/s to the left. After the collision, the 600kg bumper car is traveling at 2 m/s at an angle of 15º above the horizontal. What are the velocity and the angle of the 400 kg bumper car? 0.88m/s @ 242.85º 3) In a pool game, the cue ball, which has an initial speed of 5m/s,
