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

So are u adding some additional catalyst
