An ore cart of mass 1200 kg is rolling at a speed of 10.8 m/s across a flat surface. A crane dumps ore into the cart from directly above it
after which the cart travels at 9.3 m/s. What mass of ore did the crane add to the cart? Assume that frictional forces with the flat surface a
negligible.
240 kg
110 kg
