Starting from rest, the boy runs outward in the radial direction from the center of the platform with a constantacceleration of 0.5 m/s2. If the platform is rotating ata constant rate θ=0.2 rad/s, determine the radial andtransverse components of the velocity and acceleration of the boywhen t = 3 s. Neglect his size.
