A 160 g air-track glider is attached to a spring with spring constant 4.40 N/m. The damping constant due to air resistance is 2.40×10−2 kg/s. The glider is pulled out 23.0 cm from equilibrium and released.(adsbygoogle = window.adsbygoogle || []).push({});

How many oscillations will it make during the time in which the amplitude decays to e^-1 of its initial value?

I have no clue how to approach this problems except that

x(t)=Ae^-bt/2m=Ae^-t/2tau

but how can I fin that amount of oscillations?

I'm confused and the dead lines in an hour

please help!
