A pendulum of length I = 2 in and mass m = 0.2 kg is swinging from the ceiling. The amplitude of the oscillation is θmax = 10 degrees.
1. Compute the total force acting on the bob at the lowest point P of the trajectory Give magnitude and direction.
2. Compute the tangential acceleration of the object at the lowest point P of the trajectory. Hint: use the second law.] Can we say that instantaneously this is a uniform circular motion?
3. If the bob was just hanging from the ceiling without swinging, would the tension in the rope be less than, greater than, or equal to the tension you found in question 2? Why?
