To form a pendulum, a 0.050 kg ball is attached to one end of a rod of length 1.2 m and negligible mass, and the other end of the rod is mounted on a pivot. The rod is rotated until it is straight up, and then it is released from rest so that it swings down around the pivot. When the ball reaches its lowest point, what are (a) its speed and (b) the tension in the rod? Next, the rod is rotated until it is horizontal, and then it is again released from rest. (c) At what angle from the vertical does the tension in the rod equal the weight of the ball? (d) If the mass of the ball is increased, does the answer to (c) increase, decrease, or remain the same? (a) Number i 4.8e0 (b) Number i 1.4e0 (c) Number i 19. (d) increase Units Units Units m/s N ° (degrees)
