Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_50

4/50 A rotary snow plow mounted on a large truck eats its way through a snow drift on a level road at a constant speed of 20 km/h. The plow discharges 60 Mg of snow per minute from its 45° chute with a velocity of 12 m/s relative to the plow. Calculate the tractive force P on the tires in the direction of motion necessary to move the plow and find the corresponding lateral force R between the tires and the road.
