A mine car, mass= 440 kg rolls at a speed of 0.50 m/s on a horizontal track. A 150-kg chunk of coal has a speed of 0.80 m/s when it leaves the chute. The chunk of coal falls into the car at a 25 degree angle. Determine the velocity of the car/coal system after the coal has come to rest in the car.

    The answer depends upon whether the 25 degree angle is tilted in the direction of motion of the car or in the reverse direction. In any case, apply conservation of horizontal momentum
