A bowling ball weighing 71.2 N (16.0 lb) is attached to the ceiling by a 3.80-m rope. The ball is polledto 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 anddirection, at this instant? (b) What is the tension in the rope at this instant?
