Finding Time in an Oscillation Problem

[sheiky989]

Homework Statement

Here on Earth you hang a mass from a vertical spring and start it oscillating with amplitude 2.4 cm. You observe that it takes 3.0 s to make one round trip.

You construct another vertical oscillator with a mass 6 times as heavy and a spring 3 times as stiff. You take it to a planet where gplanet = 8.0 N/kg. You start it oscillating with amplitude 3.9 cm. How long does it take for the mass to make one round trip?

Homework Equations

x = Acos(wt)

w= sqrt(ks/m) = 2pi/T

T= 2pi/w

f = 1/T = w/2pi
