... The first step is to determine the speed of the carousel at the location of your sister. The radius is 4 m, so the circumference at that point is 8 m or 25.1 m. The time for one revolution is 8 s, so the speed is 8 / 8 = or 3.14 m/s. Then the centripetal force is m v2 / r = 20 * 2 / 4 = 49.3 ...
