4. a) A 1-kg mass stretches a spring 5 cm. How far does the spring stretch when it supports 3-kg? b) Recall that weight is a force and according to Newton's 2nd Law W= mg. Useg = 9.8 m/s^2 to determine the weight of the 1 kg mass. c) Use your determined weight for the F in the formula (weight is a Force) and Use Hooke's Law F = -kx, rearrange the terms to solve for the spring constant k in units of (N/cm).

A spring has a length of 0.200 m when a 0.300kg mass hangs from it, and a length of 0.750 m when a 1.95-kg mass hangs from it. (a) What is the force constant of the spring? (b) What is The unloaded length of the spring?
. A hand exerciser utilizes a coiled spring. A force of 89.0 N is required to compress the spring by 0.0191m. Find the force needed to compress the spring by 0.0508 m. What is the value of the spring constant for this unit?
Hooke's law states that F=kx where F is the spring force. Based on my knowledge, force applied to a spring will change in respect to the elongation of the spring so the force applied is not constant. Then what does F stand for since force on spring is varying? The average force needed to pull the spring over the distance or the maximum force a person has to apply? Or does the understanding have a factual error. Thanks so much!
