Hooke's Law States That the Magnitude of Force, F, Required

question 6

Multiple Choice

Hooke's law states that the magnitude of force, F, required to stretch a spring x units beyond its natural length is directly proportional to x. If a force of 2 pounds stretches a spring from its natural length of 10 inches to a length of 10.7 inches, what force will stretch the spring to a length of 11.5 inches? Round answer to nearest hundredth.

Definitions:

Z-score

A numerical indicator that shows how a value compares to the average of a set of values, expressed as the number of standard deviations away from the mean.

Normally Distributed

A type of continuous probability distribution for a real-valued random variable, characterized by a symmetric bell-shaped curve.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the individual values deviate from the mean.

Standard Deviation

A measure of the amount of variation or dispersion in a set of values, representing an average distance from the mean.
