A particle is suspended from a vertical spring which is executing S.H.M. of frequency 5 ~Hz . The spring is unstretched at the highest point of oscillation. Maximum speed of the particle is ( g =10 ~m / s ^2 )

Options

  1. A1 m / s
  2. B1 4 m / s
  3. C1 2 m / s
  4. Dm / s

Correct answer

A. 1 m / s

Step-by-step solution

Amplitude of SHM, A = mg k = g ^2 =2 f =2 5=10 aligned & A = 10 100 ^2 = 1 10 ^2 & ~V _ = A = 1 10 ^2 10 = 1 m / s aligned
