hi! can you do this problem for me please?
2. A simple pendulum of length of 0.7 m is displaced by a small angle from its equilibrium position to the right, and then released from rest. The speed of the bob at the lowest point is 0.92 m/s. a) What is the frequency of the oscillation? b) What is the angular amplitude of the oscillation? c) Calculate the time required for the bob to move from the vertical position (first pass) to an angular displacement of 0.2 rad.
