A bowling ball weighing 71.2 N (16.0 Ib) is attached to the ceiling by a 3.80-m rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. As the rope swings through the vertical, the speed of the bowling ball is 4.20 m/s.
(a) What is the acceleration of the bowling ball, in magnitude and direction, at this instant?
(b) What is the tension in the rope at this instant?
