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 2.48 x 10^4 kg is moving at a speed of 3.84 m/s. After the collision, the 1.5 kg ball moves to the right at 2 m/s. {{m}_{1}}{{v}_{1}}+{{m}_{2}}{{v}_{2}} &=\left( {{m}_{1}}+{{m}_{2}} \right){{v}_{f}} \\ A. 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. If the cars lock together as a result of the collision, what is their common speed just afterward? After the collision, the 1.5 kg ball moves to the right at 2 m/s. Things to Do Restaurants Flights Vacation Rentals Travel Stories Cruises Rental Cars Tripadvisor Plus More. What is the speed of the three cars after the collision? A 85 kg running back is moving at +12 m/s and strikes a 125 kg linebacker moving at -8.0 m/s. Two freight Cars , each with a mass of 3.0 x 10^5 kg collide and stick together . The truck and car are locked together after the collision and move with speed 8 m/s. A 40,000 kg railroad car initially traveling at 10 m/s collides in elastically 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 same di. Here, m1 and m2 are the mass of the cars and u1 and u2 are their respective, A: The given data are: If the cars lock together as a result of the collision, (a) What is their common speed afterward? No one has answered this question yet. 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 2.06 m/s. A car of mass 10,000 kg and speed of 10 m/s is coming onto a track where another set of coupled cars of total mass 50,000 kg is sitting at rest. 10,000*10 + 5000*V2 = 10,000*8 + 5000*8, Near Train Stations. A railroad car of mass 2.55 times 10^4 kg is moving with a speed of 3.94 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 1.97 m / s. A railroad car of mass 2.46 \times 10^4 kg, is moving with a speed of 4.11 m/s. (e) Substitute values, obtaining the numerical value for vf, their speed after the collision. Rain falls vertically. The second mass is, A: Given data: The cars stick together. Perform the following practice problems on a seperate sheet of notebook paper. What is the change in momentum of the cart?
