A mass is oscillating on the end of a spring. The distance, $y$, of the mass from its equilibrium point is given by the formula
$$y=3 z \cos (12 \pi w t)$$
where $y$ is in centimeters, $t$ is time in seconds, and $z$ and $w$ are positive constants.

(a) What is the furthest distance of the mass from its equilibrium point?
distance = cm

(b) How many oscillations are completed in 1 second?
number of oscillations =
