An open-topped freight car with mass 24,000 kg is coasting without friction along a level track. It is raining very hard, and the rain is falling vertically downward. Originally, the car is empty and moving with a speed of 4 m/s

(a) What is the speed of the car after it has collected 3000 kg of rainwater?

(b) Since the rain is falling downward, how is it able to affect the horizontal motion of the car?

Four railroad cars, each of mass 2.70 104 kg, are coupled together and coasting along horizontal tracks at speed vi toward the south. A very strong but foolish movie actor, riding on the second car, uncouples the front car and gives it a big push, increasing its speed to 3.85 m/s southward. The remaining three cars continue moving south, now at 2.00 m/s. (a) Find the initial speed of the four cars. m/s (b) By how much did the potential...

The car of an amusement park ride with mass m=90 kg slides along a track that we can consider as frictionless. Initially it is at position A at a height 11.6 m above the ground and moving with speed 4.0 m/s. It moves through a valley and over a second hill at position B at a height 7.3 m above the ground. Find the speed of the car when it is at position B.
