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 3.10 ✕ 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?

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.45 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 35.5 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target? A railroad car of mass 2.35 times 10^4 kg moving at 2.50 m/s collides and couples with two coupled railroad...
A railroad car of mass 2.42 × 104 kg is moving with a speed of 3.84 m/s.
