Solve the all parts of following problem given below:
Problem: A ball of weight 75 N is attached to the ceiling by a 3.80-m mass less rope. The ball is pulled to one side and released, swinging back and forth like a pendulum. As the rope swings through the vertical, the speed of the bowling ball is 4.20 m/s.
Part A: What is the acceleration of the ball (magnitude and direction) at this instant?
Part B: What is the tension in the rope at this instant?
