Starting from rest the boy runs outward in the

Starting from rest, the boy runs outward in the radialdirection 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 and transverse components of the velocity and acceleration of the boywhen t = 3 s. Neglect his size.

The answers in the back of the book are vr=1.50 m/s, vθ= 0.450 m/s, ar=.410 m/s2, and thenaθ= 0.600 m/s2.
