Rates of change are the change of a quantity over another.
The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
The given parameters are:
-- the amplitude
--- the period
The position of the mass is modeled by:

Where:

So, we have:


becomes


Differentiate


When t = 2.1, we have:




Approximate

Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
