- Two cars approach an ice-covered intersection. One car, of mass 1.10 103 kg, is initially traveling north at 10.1 m/s. The other car, of mass 1.55 103 kg, is initially traveling east at 10.1 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:9. An object (A) of mass m AA= 28.0 kg is moving in a direction that makes angle of 36° south of east with a speed v AA= 5.00 m/s, while object (B) of mass m BB= 18.5 kg is moving due north with a speed v BB= 8.00 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision.An 80 kg running back moving at 5.0 m/s attempts to dive directly across the goal line for a touchdown. Just as he reaches the line, he is met head-on in mid-air by two 75 kg linebackers both moving in the direction opposite the running back at 2.8 m/s. They all become entangled as one mass.
