A wagon weighing 5.00 x 103 N is pulled along amuddy,horizontal road by a 500-kg horse. The coefficient ofrollingresistance between the wagon wheels and the road is 0.200.(a) If the wagon is pulled at constant speed, what force mustthehorse exert on the ground to pull the wagon? (b) If the wagonisaccelerated from rest to a velocity of 5.00 m/s in 5.00 s,whatforce must the horse exert on the ground?
