- Cheryl (mass = 50 kg) and Jared (mass = 62 kg) occupy separate 36-kg bumper carsCheryi gets her car cruising at 3.6 m/s and collides head-on with Jared who is moving the opposite direction at 1.6 m/s . After the collisionCheryl bounces backwards at 0.5 m/s Assuming an isolated system, determine Jared's post- collision speed.Two cars approach an ice-covered intersection. One car, of mass 1.27 103 kg, is initially traveling north at 11.6 m/s. The other car, of mass 1.64 103 kg, is initially traveling east at 11.6 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. magnitude direction north of eastplease answer all 1. A block of mass 1.71 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 3.50 m/s. It eventually collides with a second, stationary block, of mass 4.04 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.71-kg and 4.04-kg blocks, respectively, after this collision? 2. Same situation as before. This time it s a block of mass 1.07 kg sliding with a constant velocity of 3.51 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.28 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision.
