In hooke's law, f s p r i n g end equals k increment x, what does the increment x stand for? a. elastic constant, a number that tells the relative strength of the spring b. the distance the spring stretches c. the amount of force acting on the spring d. the constant of gravity

option b, the distance the spring stretches.

Hook's law is: F = - K Δx

Where:

F stands for the force that the spring exerts

K is stands for the constant of the spring

Δx stands for the distance the spring is displaced from the equilibrium point.

And the negative sign is due to F is opposite to the direction in which the spring is away from the equilibrium point.

    5.5 n======    assuming that      we have      m = 0.145 kg    a = 38 m/s²therefore    5.51 n, but two significant figures.final answer: 5.5 n
