A 3-kg toy car with a speed of 6 m/s collides head-on with a 2-kg car traveling in the opposite direction with a speed of 4 m/s. If the cars are locked together after the collision with a speed of 3.435 m/s, how much kinetic energy is lost?
A 3 kg toy car with a speed of 5 m/s collides head-on with a 2 kg car traveling in the opposite direction with a speed of 3 m/s. If the cars are locked together after the collision with a speed of 1.80 m/s, how much kinetic energy is lost?
A 3 kg toy car with a speed of 8 m/s collides head-on with a 2 kg car traveling in the opposite direction with a speed of 5 m/s. If the cars are locked together after the collision with a speed of 2.80 m/s, how much kinetic energy is lost?
A 3kg toy car with a speed of 6 m/s collides head on with a 2kg car traveling in the opposite direction with a speed of 4m/s. If the cars are locked together after the collision with a speed of 2m/s, how much kinetic energy is lost?
A 7,500-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 7 m/s. Compute how much kinetic energy was "lost" in this inelastic collision.
A railroad car of mass 2.30E+4 kg moving with a speed of 3.00 m/s collides and couples with two other coupled railroad cars each of the same mass that are already moving in the same direction at a speed of 1.50 m/s. What is the speed (in m/s) of the three coupled cars after the collision? Tries 0/3 How much kinetic energy (in J) is lost in the collision? Tries 0/3
A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. Assume that any other unbalanced forces are negligible. a. What is the speed of the wreckage just after the collision? b. In what direction does the wreckage move just after the collision? c. How much kinetic energy is lost in this collision.
A railroad car of mass 3.10 ✕ 104 kg moving at 3.40 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. (a) What is the speed of the three coupled cars after the collision? (b) How much kinetic energy is lost in the collision?
A railroad car of mass 3.15 ✕ 104 kg moving at 2.75 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. (a) What is the speed of the three coupled cars after the collision? (b) How much kinetic energy is lost in the collision?
A railroad car of mass 3.25e4 kg is moving at 3.25 m/s collides and couples with two couples railroad cars, each of the same mass as the single car and moving in the same direction at 1.20m/s. A) what is the speed of the three coupled cars after the collision? B) how much kinetic energy is lost in the collision?
