A 10,000-kg railroad car A, traveling at a speed of 24.0 m/s A: The given system is closed which means there is no external force is acting on the system. Now when the railroad cars collide and have a common velocity, their momentum will incorporate the masses of the two railroad cars. Impulse=p=mvf-vi=0.427kg22.6m/s--16.0m/s=16.48kgm/s, A: Answer: (A) It collides and couples with three other coupled railroad cars, each of the same mass, A railroad car of mass 2.50 x 10^4 kg is moving with a speed of 3.87 m/s. Mass of first particle (m1) = 3.00 kg What is the speed of the two cars after coupling? Tours Add a Place Travel Forum Airlines Travel Guides Road Trips Help Center. The cars stick together. A 27,000 kg train car moving due east at 40 m/s collides and couples with a 13,000 kg train car that is initially at rest. So, it was interesting to visit it again. How much mec. other forms of energy? A: For the given case of inelastic collision, A: Momentum is defined as the product of mass and velocity. A railway car having a total mass of 5.8 \times 10^5 kg, moving with a speed of 9.1 km/h, strikes another car that has a mass of 8.7 \times 10^5 kg and is initially at rest. a) What is the speed of the three coupled cars after the, A railroad car of mass 3.00 x 10^4 kg moving at 3.50 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. A 10,000-kg railroad car, A, traveling at a speed of 24.0 m/s strikes an identical car, B, at rest. A {eq}12000\text{-kg} Each railroad car has a mass of 75000 kg. Wha. 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 2.02 m/s. One was initially moving at 2.2 m/s , and the other was at rest. A initial velocity of the linebacker is, A: Given data If the gun has a mass. A 5000-kg freight car moving at 2 m/s collides with a 10000-kg freight car at rest. 1 See answer Advertisement skyluke89 Answer: 10 m/s Explanation: (b) If, Use g=9.8 m/s2 a 980,000 J b 420,500 J c 98,000 Nm d 14,500 J, is 1000 000 less than 2 183 486 is 1 000 000 more than 746 000 is 1 000 000 less than 624 327 207, 2. An airplane flying acroos the sky. Velocity of first particle (v1) = +3.00 m/s The mass of the blue puck in Figure P9.44 is 20.0% greater than the mass of the green puck. (a) What is the initial momentum of the first car? The truck and car are locked together after the collision and move with speed 8 m/s. The cars lock bumpers and skid off together with the wheels. In Example #1 (linear momentum lecture), a railroad car, A, traveling at a speed of 24.0 m/s strikes a car, B, at rest. If the two cars stick together and move off with a velocity of 6 m/s, show that the mass of the second car is 13950 kg. (a), A railroad car of mass 2.35 x 10^4 kg moving at 2.80 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. How much kinetic energy is lost in the collision? Determine the following. First week only $4.99! A 40,000 kg railroad car initially traveling at 10 m/s collides inelastically with a 20,000 kg railroad car initially at rest. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and moving in the sa. What is their speed after the collision?
