You push on a spring whose stiffness is 100 N/m, compressing it until it is 4 cm shorter than its relaxed length.
1) In the formula sheet provided, which equation can be used to calculate the magnitude of the spring force?
2) The magnitude of the force the spring now exerts on your hand is: ∣∣Fs∣=
3) If the relaxed length of the spring is 10 cm, the final length of the spring is L=
