The velocity at mean position and acceleration at the extreme position have the phase difference of

Options

A. `pi//2` rad
B. `pi` rad
C. `pi//4` rad
D. `3pi//4` rad

Answer

A

Explanation

The velocity and acceleration have a phase of `(pi)/(2)`. The mean and extreme position have a phase of `(pi)/(2)`, therefore a phase of `pi`.
