Question

Physics

A simple pendulum with mass m = 1.5 kg and length L = 2.49 mhangs from the ceiling. It is pulled back to an small angle of θ =9.5° from the vertical and released at t = 0.

What is the magnitude of the force on the pendulum bobperpendicular to the string at t=0?

What is the maximum speed of the pendulum?

What is the angular displacement at t = 3.67 s? (give the answeras a negative angle if the angle is to the left of thevertical)

What is the magnitude of the tangential acceleration as thependulum passes through the equilibrium position?

What is the magnitude of the radial acceleration as the pendulumpasses through the equilibrium position?

Which of the following would change the frequency of oscillationof this simple pendulum?

increasing the mass

decreasing the initial angular displacement

increasing the length

hanging the pendulum in an elevator accelerating downward
