A simple pendulum has a mass of 0.350 kg and a length of 7.00 m. It is displaced through an angle of 8.0° and then released. Using the analysis model of a particle in simple harmonic motion, calculate the following. (Give your answer to the thousandths place.)

(a) What is the maximum speed of the bob?
-I already found it to be 1.156 m/s

(b) What is the maximum angular acceleration of the bob?

(c) What is the maximum restoring force of the bob?

(d) Solve parts (a)through (c) by using other analysis models. (Hint: you may need to use separate analysis models for each part.)

whoops, that says maximum speed (m/s) and max angular velocity (rad/s^2) ...they got cut off

anonymous · Answer

solved it all except for the maximum angular acceleration of the bob...can somone help me with just that one question?

mgh = Inertia * angular acceleration =  m H^2 * angular acceleration
mg(H -H cos $ \theta$) = m H^2 * angular acceleration
