A bowling ball weighing 70.2 N (= mg ) is attached to the ceiling by a 2.80 m rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. The ball is initially pulled back so it is a vertical height of 2.3 m above the lowest point of the ball's swing. When the ball is at its lowest point in its swing, what is the acceleration of the bowling ball, in magnitude and direction?

Professor Walter Lewin, for his famous Physics experimental demonstration, hanged a bowling ball from the ceiling by a rope. He then pulls the ball away from its equilibrium position and holds it adjacent to his nose, as shown. He releases the ball so that it swings directly away from him. Does he get struck by the ball on its return swing? What is he trying to show in this demonstration?

A 0.37 kg ball is attached to a 0.71 m long string. The other end of the string is then attached to the ceiling in order to create a pendulum. It is then drawn back such that the string makes an angle of 50 degrees relative to the ceiling and then released from rest. How fast is the pendulum traveling when the string makes an angle of 20 degrees relative to the vertical

The length of a simple pendulum is 0.85 m and the mass of the particle (the "bob") at the end of the cable is 0.26 kg. The pendulum is pulled away from its equilibrium position by an angle of 7.75° and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple harmonic motion. (a) What is the angular frequency of the motion? rad/s (b) Using the position of the bob at its lowest...

A simple pendulum is made from a 0.760-m-long string and a small ball attached to its free end. The ball is pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed?
