A 2.00×104 kg railroad car is rolling at 6.00 m/s when a 7000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded? -Please show how you do each step, I really want to learn how to understand this if you have the time to. Thank you.
A 2.00×104 kg railroad car is rolling at 2.00 m/s when a 7000 kg load of gravel is suddenly dropped in. Part A What is the car's speed just after the gravel is loaded? Express your answer with the appropriate units.
A 10,000 kg railroad car is rolling at 2.00 m/s when a 2000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded?
A 10,000 kg railroad car is rolling at 8.00 m/s when a 6000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded? Express your answer with the appropriate units.
A 6450-kg railroad car travels alone on a level frictionless track with a constant speed of 20.0 m/s . A 3850-kg load, initially at rest, is dropped onto the car. Part A What will be the car's new speed? Express your answer to three significant figures and include the appropriate units.
A railroad car with a mass of 1.95 ✕ 104 kg moving at 2.88 m/s joins with two railroad cars already joined together, each with the same mass as the single car and initially moving in the same direction at 1.56 m/s. (a) What is the speed of the three joined cars after the collision? m/s (b) What is the decrease in kinetic energy during the collision? J
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?
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 2.95 ✕ 104 kg moving at 3.10 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? m/s (b) How much kinetic energy is lost in the collision? J
A 12100 kg railroad car is coasting on a level, frictionless track at a speed of 19 m/s when a 4790 kg load is dropped onto it. If the load is initially at rest, find the new speed of the car and the % change of the kinetic energy.
