EXAM I, PHYSICS 1306

Calculate the centripetal acceleration . aR (m/s2) of point . P. at time . t = 20 s. What is the vector direction of . aR? Calculate the tangential acceleration atan (m/s2) of point . P. at . t = 20 s. atan. is a vector tangent to the dashed circle. As I stressed in our brief discussion, the angular acceleration of the disk must be caused by a ... ................
