Question

A 1.050 kg air-track glider is attached to each end of the track by two coil springs. It takes a horizontal force of 0.700 N to displace the glider to a new equilibrium position, x= 0.190 m.

Find the effective spring constant of the system.

Answer: 3.68 N/m

The glider is now released from rest at x= 0.190 m. Find the maximum x-acceleration of the glider.

Answer: 6.67x10^-1 m/s^2

Find the x-coordinate of the glider at time t= 0.450T, where T is the period of the oscillation. Need Help with this one

Explanation / Answer

c)The position can be give by:

x=0.19Cos(2pi*t/T)

x=0.19*Cos(2pi*0.45)=-0.181m ( Use 3 significant figures because it is so in the question too). This is the correct answer.
