A slowly moving flat car is 12.0 m long passing apoint at straight road at 10 kph. A boy beside the road near to that point tosses rocks onto the moving flat car at the rate of one per second, (a) If the first rock just hits the front edge of the car, how many rocks will fall on to that car ? (b) How many rocks will fall onto that car if the car begins to accelerate at `0.5 m//s^(2)`, just as the first rock hits the car ?
