Question

A mass is hanging from a spring that is moving as v(t) = 4.9sin(4.5t). So the velocity is at 0 m/s on a periodic basis. For example, when t = 0 s, the velocity is 0 m/s. What is the ACCELERATION of the mass when the velocity at the NEXT possible time (after 0 seconds) where the velocity is 0 m/s? Report your answer to the tenth's decimal place.
