The disk rolls without slipping on the horizontal surface, and at the instant represented, the center O has the velocity and acceleration shown in the figure. For this instant, the particle A has the indicated speed u and time rate of change of speed u˙, both relative to the disk. Determine the absolute velocity and acceleration of particle A.
