Starting from rest, a boy runs outward in the radial direction from the centre of a platform with a constant acceleration of 0. 5 m/s2. If the platform is rotating at a constant angular velocity of 0. 2 rad/s, determine the radial and transverse components of the velocity and acceleration of the boy after 3s.
