A horizontal merrygoround is initially at rest. At t = 0, it is given a constant angular acceleration a = 0.0840 radg'sz, which increases its angular velocity. A 25.9 kg child sits at 2.30 m from the axis of rotation. (a) At t = 8.30 5, determine the centripetal force acting on the child. -|' \"N (b) At t = 8.30 5, determine the direction of the net force acting on the child. Specify the angle from the radially inward direction. 'i o (c) Through how many radians has the merry-go-round rotated within that 8.30 s time? -' ]rad
