A simple pendulum of length 0.80m is given a small initial angular amplitude of 6.0∘. Take g=9.8m s−2.
a. (a) Convert the given angular amplitude to radians, retaining three significant figures.
b. (b) Calculate the maximum linear displacement of the bob from its mean position.
c. (c) Determine the magnitude of the tangential restoring force acting on a 0.25kg bob at the extreme position.
