Hey, could someone help me with this qs pls!

A particle P describes SHM, making three complete oscillations per second. At a certain instant, P is at the Point O and is moving at its maximum speed of 5ms-1.

Find the Speed of P 0.05s after it passes through O.

You can model SHM motion using

 x = A \sin( \omega t)

 v = \frac{dx}{dt} = A \omega \cos(\omega t)

 A \omega is the max speed.

 \omega = 2 \pi f = 6 \pi because three complete oscillations per second.

Make sure when you do the trigo computation using your calculator, it is set to radian mode.
