Question

Been on this problem for 2 hours now:
Four identical springs support equally the weight of a 1150kg car.

If a 91kg driver gets in, the car drops 6.8mm . What is k for each spring?

The car driver goes over a speed bump, causing a small vertical oscillation. Find the oscillation period, assuming the springs aren't damped.


Im assuming for Part A its K=mg/x then divide by 4, so what am I doing wrong?? :/

Answer 1

you using meters for 'x'?

Answer 2

other than that, it's correct.

Answer 3
