A bowling ball weighing 71.8 N is attached to the ceiling by a rope of length 3.83 m. 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 4.50 m/s.

What is the acceleration of the bowling ball, in magnitude and direction, at this instant?

What is the tension in the rope at this instant?
