An object of mass 2 ~kg is attached to a spring with spring constant 8 Nm ⁻¹ . If the object is executing simple harmonic motion then the number of cycles it completes in 66 ~s is

Options

  1. A21
  2. B16
  3. C28
  4. D12

Correct answer

A. 21

Step-by-step solution

Time period of a spring mass system is T=2 m k Here, m=2 ~kg and k=8 ~N / m So, time for 1 oscillation, T=2 2 8 =2 1 2 or T= s Number of cycles in 66 seconds is n= t T = 66 n= 66 7 22 =21 Hence, object complete 21 oscillations in given time.
