Problem: The position of a mass oscillating on a spring is given by x = (6.2 cm)cos[2πt/(0.79s)]. What is the frequency of this motion? When is the mass first at the position x = − 6.2cm?

FREE Expert Solution

The position a mass oscillating on a spring can be expressed as:

x(t)=Acos(2πTt)=Acos(ωt)

Frequency, f = 1/T
