A boy shoves his stuffed toy zebra down a frictionless chute. It starts at a height of 1.21 m above the bottom of the chute with an initial speed of 1.39 m/s. The toy animal emerges horizontally from the bottom of the chute and continues sliding along a horizontal surface with a coefficient of kinetic friction of 0.2470. How far from the bottom of the chute does the toy zebra come to rest? Assume ?=9.81 m/s

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 EXPLAIN IN DETAIL.
