What is the cars speed after the loading is completed

Reference no: EM13339588

An open train car, with a mass of 2150 kg, coasts along a horizontal track at the speed 2.43 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 3.25 s at the rate of 431 kg/s. What is the car's speed after the loading is completed? Ignore rolling friction (as unrealistic as that may be).
