A horizontal merry-go-round is initially at rest. At t = 0, it is given a constant angular acceleration ? = 0.0710 rad/s2, which increases its angular velocity . A 23.5 kg child sits at 2.35 m from the axis of rotation.
(a) At t = 9.70 s, determine the centripetal force acting on the child.
________ N
(b) At t = 9.70 s, determine the direction of the net force acting on the child. Specify the angle from the radially inward direction.
