.5 A small block is free to slide inside of a slot in the rotating platform, as shown in Figure 3.13. It moves outward relative to the platform with a speed of r 7t m/s. If the platform is rotating clockwise at a constant rate of 4.5 rad/sec and the block starts initially at rest from the center of the platform, what are the velocity and acceleration of the block after 0.5 seconds?
