The position of the oscillating object in cm, relative to a fixed point is given as a function of time, t, in seconds by:
a) Find an expression for the velocity and acceleration of the object. (Remember velocity is the derivative of position, and acceleration is the derivative of velocity)
I don't have a lot of experience with physics at all so I'm really unsure about how I should approach this. I tried getting the derivative of the position as the hint suggests, but the answer I got was 0 because I was deriving a constant which can't be right.
