It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the same dire, A railroad car of mass 24,300 kg is moving with a speed of 4.17 m/s. A, A railroad car of mass 15000 kg and velocity 5 m/s collides completely inelastically with a stationary railroad car of mass 25000 kg and couples to it. a) What is the velocity of the two cars just. t is time period and m v is an impulse, A: Given:- What is the speed of the three coupled cars after the collisio, A railroad car of mass 2.59104 kg is moving with a speed of 4.16 m/s. The cars stick together. A 2500 kg truck runs into the rear of a 1000 kg car that was stationary. (e) Substitute values, obtaining the numerical value for vf, their speed after the collision. Wha. Do. Learn the concepts of inelastic collision and elastic collision. strikes an identical car, B, at rest. mB= 0.4 kg (a) What is the speed of the three coupled cars after, A railroad car of mass 2.75 times 10^4 kg moving at 2.70 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. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the same direction with an initial speed of 1.95 m/s. Determine the following. A train car with mass m_1=511 kg is moving to the right with a speed of v_1=7.7 m/s and collides with a second train car. A car traveling next to you at the same speed you are traveling. What is the magnitude of the kinetic energy (in J). If the cars lock together as a result of the collision, what is their common speed afterward? A 40,000 kg railroad car initially traveling at 10 m/s collides inelastically with a 20,000 kg railroad car initially at rest. (e) The velocities cannot be determined without knowing the mass of each ball. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the same, A railroad car of mass 2.49 x 10^4 kg is moving with a speed of 3.84 m/s. a) What is, A 12000 kg train engine moving at 2.2 m/s locks into 3 boxcars with a total mass of 25000 kg sitting still. If the cars lock together as a result of the collision, what is their common speed just afterward? They are released from rest simultaneously and collide elastically in the trough of the track. What is their speed after the collision? Initial velocity of, A: Impulse is given by If the cars lock together as a result of the collision, what is their common speed just afterward? A railroad car of mass 2.2 * 10^4 kg moving at 2.50 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. 3. same as 1, if they stick together, final momentum (85+125)V solve for v. You can ask a new question or browse more Physics ~ CONSERVATION OF MOMENTUM ~ questions. What is their common speed just afterwards if (a). What is the resulting speed of the combined cars. mcvci+mtvti=mcvcf+mtvtf A 5000-kg freight car moving at 2 m/s collides with a 10000-kg freight car at rest.
