A simple pendulum consists of a 3.0kg mass attached to a 5.0m long light rope. The upper end of the rope is fixed on the ceiling of the lecture theatre. At time t = 0s the rope holding the mass makes an angle 0.040rad to the left of its equilibrium position moving to the right at 0.056rad/s .
a) What is the maximum angle the rope makes with the vertical? answer = 0.057rad
b) When is the first time after t = 0.0s when the rope makes an angle θ = 0? answer = 0.56s
c) What is the time rate of change of θ (ie d/dtθ) at 2.3s? answer = −0.061rad/s
Please post detailed solutions. The answers are included. Thank you.
