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 2zcos(14πwt) where y is in centimeters, t is time in seconds, w and t and are positive constants.
What is the furthest distance (cm) of the mass from its equilibrium point?
How many oscillations are completed in 1 second?
