Question

A simple pendulum has a mass of 0.550 kgand a length of 4.00 m. It is displacedthrough an angle of 12.0° and then released. Solve this problem by usingthe simple harmonic motion model for the motion of the pendulum. (a) What is the maximum speed?
...................m/s

(b) What is the maximum angular acceleration?
2 rad/s2

(c) What is the maximum restoring force?
3 N (a) What is the maximum speed?
...................m/s

(b) What is the maximum angular acceleration?
2 rad/s2

(c) What is the maximum restoring force?
3 N

Explanation / Answer

   m = 0.550 kg    L = 4.00 m     = 12.0o    using the simple harmonic motion model weget that    A = r        = 4.00 m 12.0o ( /180o)        = ........ m     = (g / L)        = ........ rad / s (a)    vmax = A            =........ m / s (b)    amax = A 2            =....... m / s2 (c)    F = m a       = ....... N            =....... m / s2 (c)    F = m a       = ....... N
