The body of a 1297 kg car is supported on a frame by four springs. The spring constant of
a single spring is 1.24 × 10
4
N/m. Four people riding in the car have a combined mass
of 259 kg. When driven over a pothole in
the road, the frame vibrates and for the ﬁrst
few seconds the vibration approximates simple harmonic motion.
What is the period of vibration of the car?
Answer in units of s

The combined spring constant of the four springs "in parallel" is four times that of a sintle spring, which is
k = 4.96*10^4 N/m
m is the total mass of car and occupants, which appears to be 1556 km.
The period of vibration is 2*pi*sqrt(m/k)
Do the calculation.
