Which one of the following statement is true for the speed `v` and the acceleration a of a particle executing simple harmonic motion?

Options

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

Answer

C

Explanation

IN SHM if v=`v_"max"`
v=0
then a=0
then `a=a_"max"`
