A ball on the end of a string is moving in circular motion as a conical pendulum as in the figure. The length L of the string is 1.70 m, the angle is 37.0 degrees and the ball completes one revolution every 2.51 seconds.
(a) What is the speed (m/s) of the ball?
(b) What is the acceleration (m/s2 ) of the ball?
