A simple pendulum performs simple harmonic motion about x =0 with an amplitude ' a ' and time period ' T '. The speed of the pendulum at x= a 2 is

Options

  1. Aa T
  2. B3 ^2 a T
  3. Ca 3 ~T
  4. Da 3 2

Correct answer

C. a 3 ~T

Step-by-step solution

aligned v & = a ^2- x ^2 At x & = a 2 , v & = a ^2- a ^2 4 & = 3 a 2 & = 2 T 3 a 2 v & = a 3 ~T aligned
