Question

The displacement x (in metre) of a particle in, simple harmonic motion is related to time t (in seconds) as

                     x = 0.01 cos (πt+π4)

                The frequency of the motion will be

 


  1. 0.5 Hz

  2. 1.0 Hz

  3. πHz


Solution

The correct option is A

0.5 Hz


Comparing given equation with standard equation,

x = a cos (ωt + ϕ), We get , a = 0.01 and ω=π

2πn=πn=0.5hz
