A 1055 kg van, stopped at a traffic light, is hit directly in the rear by a 690 kg car traveling with a velocity of +2.45 m/s. Assume that the transmission of the van is in neutral, the brakes are not being applied, and the collision is elastic. What is the final velocity of each vehicle?(a) car m/s(b) van m/s

Object 1 with a mass of 4.70 kg, moving right at a speed of 7.80 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.30 kg moving left at a speed of 10.6 m/s. After the collision, the Object 1 is moving left at 2.40 m/s. 10. What is true about the total momentum before and after the collision?

Two otters are sliding toward each other on a muddy frictionless horizontal surface. One of them, of mass 7.5 kg, is sliding to the left at 5.0 m/s, and the other, of mass 5.75 kg, is moving to the right at 6.00 m/s. They hold fast to each other after they collide. What is the magnitude of the velocity of these otters right after they collide? O 0.116m/s 0.236m/s O 0.441m/s O 0.226m/s
