Question 3 (10 marks) A car A of mass ma is moving at a velocity VA...
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 1490 kg car moving east at 17.0 m/s collides with a 1820kg car moving south at 15.0 m/s, and the two cars comnect together. What is the magnitude of the velocity of the cars right after the collision? what is the direction after collision? How much kinetic energy was converted to another form during the collision?
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?
A railroad car of mass 2.95 ✕ 104 kg moving at 3.10 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s.
