A glider on an air track is connected by springs to either end of the track. Both springs have the same spring constant, k, and the glider has mass M.
Determine the frequency of the oscillation, assuming no damping, if k = 145N/m and M = 230g .
It is observed that after 58 oscillations, the amplitude of the oscillation has dropped to one-half of its initial value. Estimate the value of ?, using x(t)=Ae??tcos??t .
How long does it take the amplitude to decrease to one-quarter of its initial value?
