2. A child has a mass of 36 kg and is sitting on a seat on an amusement park ride. The ride makes the seat move up and down. Determine the normal force acting on the child when the child is (a) moving up at a constant velocity of 12 m/s [ans: 350 N [up]] (b) moving down at a constant velocity of 14 m/s [ans: 350 N [up]] (c) accelerating down at 1.8 m/s² [ans: 290 N [up]]
