A 1190-kg flatbed train car rolls along frictionless tracks at a
speed of 0.132 m/s. A 62.2-kg man stands on the flatbed and, in
order to stop the car, runs to the edge and jumps off.

An open train car, with a mass of 2030 kg, coasts along a horizontal track at the speed 2.33 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 3.41 s at the rate of 425 kg/s. What is the car\'s speed after the loading is completed? Ignore rolling friction (as unrealistic as that may be).

Suppose that while a mining cart is rolling along a straight, frictionless, horizontal track with some initial speed, it starts to rain. If the rain falls vertically into the cart and begins to accumulate within it, flooding the cart, determine the following 19. is the momentum of the system conserved in the horizontal direction? a. Yes b. No 20. Is the momentum of the system conserved in the vertical direction? a. Yes b. No 22.If a 1200 kg train car...

One train car of mass 50,000 kg (50 Mg) is moving 6.0 m/s to the south on a frictionless track and couples with another car of mass 20,000 kg (20 Mg). The final velocity of the now-coupled cars is 1.8 m/s to the south. Find the velocity of the second car before the coupling. (Hint: The direction is important!)
