If Car A, with mass m, is moving north with a speed v, collides, Car B, with mass 2m, is moving south with a speed 0.5v. If the cars have an inelastic collision, the final velocity of Car A is -v.
A railroad car of mass M moving at a speed v1 collides and couples with two coupled railroad cars, each of tesam mass M and moving in the same direction at a speed V2 (a) What is the speed vfof the three coupled cars after the collision in terms of v, and v2 11 +2 2 b) How much kinetic energy is lost in the collision? Answer in terms of M, v and v2 KE,-KE

A bumper car with mass m1-119kg is moving to the right with a velocity of v-4.5 m/s. A second bumper car with mass m2- 84 kg is moving to the left with a velocity of v2- 3.7 m/s. The two cars have an elastic collision. Assume the surface is frictionless
Please answer and show work!! 4) A 1kg object is moving with a velocity of 6 m/s to the right. It collides and sticks to a 2kg object moving with a velocity of 3 m/s in the same direction kinetic energy is lost in the collision? 5) A 2kg mass moving with a velocity of 7 m/s collides elastic ally with a 4kg mass moving in the opposite direction of 4 m/s. The 2 kg mass reversed direction after the...
4) A rail road car of mass 2.5 x 10 kg is moving with a speed of 4 m/s. It collides and couples with three other coupled rail cars, each of the same mass as the single car and moving in the same direction with the initial speed of 2 m/s. a) What is the speed of the four cars after collision? b) How much mechanical energy is lost in this inelastic collision?
