A 9-month-old boy is pushing down on his Fisher-Price Popcorn Popping walker toy. The toy has a mass of 4 kg and is moving with a constant velocity of 2.3 m/s. The boy is pushing down with a force at an angle of 45owith respect to the ground. There is a frictional force of 30 N acting on the toy. Determine the force of the boy acting on the handle. Ans:42.4N
