An ore cart of mass 1200 kg is rolling at a speed of 10.8 m/s across a flat surface. A crane dunks 496 kg of ore into the cart directly above it. How fast does the cart move after being loaded with ore? Assume that frictional forces with the flat surface are negligible.

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
