Question

Which one of the following statements is true for the velocity n and the acceleration a of a particle executing simple harmonic motion ?

• A. When v is maximum, a is zero
• B. When v is zero, a is zero
• C. When v is maximum, a is maximum.
• D. Value of a is zero, whatever may be the value of v

Answer 1

Answer: (A)

When v is maximum, a is zero

Answer 2

In SHM, Velocity

$v = \omega\sqrt{A^{2} - x^{2}}$

Acceleration $a = - \omega^{2}x$

When x = 0, $v = \omega A$ = maximum and a =0

When x = A, v =0 and a = $- \omega^{2}A =$maximum
