(a) Can a particle moving with instantaneous speed 8.00 m/s on a path with radius of curvature 4.00 m have an acceleration of magnitude 20.00 m/s2?
If the answer is yes, explain how it can happen; if the answer is no, explain why not.
(b) Can it have an acceleration of magnitude 13.00 m/s2?
If the answer is yes, explain how it can happen; if the answer is no, explain why not.
