In an elastic collision, a 400-kg bumper car collides directly from behind with a second, identical...
1 Elastic collision A bumper car of mass m1 = 300kg is initially moving to the right at velocity V1, before = 8m/s and collides head-on with another bumper car of mass m2 = 200kg that is motionless, V2, before = 0. After the collision, the heavy bumper car is moving at a speed of v1,after = 1.6m/s. (a) (5 pts) Calculate the total kinetic energy before the collision (b) (5 pts) Calculate the kinetic energy of the heavy car...
A 100 kg bumper-car at a fairground (carA) is rolling along a level surface in the positive x-direction at a speed of 1.00 m/s. It collides with a second 120kg car (car B) which is moving in the same direction at a speed of 0.10 m/s. If the cars stick together after the collision, what is their common velocity?
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 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 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 car with mass 1500 kg traveling east at 25 m/s collides at an intersection with a 2500kg van traveling north at a speed of 20 m/s. Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision and assuming no friction.
A 1500-kg car traveling east at 50 m/s collides with a 2200-kg truck traveling north at 66 m/s. The car and truck become entangled and slide to a stop. What is the final speed immediately after the collision? What angle with respect to the east direction do the entangled vehicles slide?
A 623 kg car moving at 18.2 m/s in the +x direction hits from behind a second car moving at 10 m/s in the same direction. If the second car has a mass of 593 kg and a speed of 19 m/s right after the collision, what is the velocity of the first car after this sudden collision? Please show work and explain. a) 26.8 m/s b) 8.74 m/s c) -9.63 m/s d) 9.63 m/s
PROBLEM FUUR (20 FUL ) A 420 kg car moving at 14.4 m/s hits from behind another car moving at 11.3 m/s in the same direction. If the second car has a mass of 590 kg and a new speed of 17.9 m/s, what is the velocity of the first car after the collision?
