A particle on a spring executes simple harmonic motion; when it passes through the equilibrium position it has a speed v . The particle is stopped, then the oscillations are restarted so that it now passes through the equilibrium position with a speed of 2y. After this change

(a) the frequency of oscillation will change by a factor of

(A) 4. (B)

(C) 2. (C)

(b) the maximum displacement of the particle will change by a factor of

(A) 4. (B)

(B) 2. (D)

c) the magnitude of the maximum acceleration of the particle will change by a factor of

(A) 4. (B)

(B) 2. (D)

(E) 1 (it remains unchanged).
