1)Suppose that you have a spring of spring constant k=100 N/m which you arrange such that the end of the spring at x=0 cm with no force applied. Now apply 10 N forces. what is the value of x? apply 5N additioal forces. what is the value of x?

2)Suppose you began the experiment of the previous paragraph after the 10 N forces were already applied. Place the meter stick so that  x=30 cm. Now apply the additional 5 N. what is the value of x on meter stick? In terms of eq f=k(x-x0), what are F, x, and z0 respectively?

Use: \(F = -k*x\)

Hang the spring from a hook such that the bottom of the spring is at mark 0. Hang some weight from the bottom of the hook. Take the reading of the bottom of the hook. This is the value of x.
Try this with more forces.

Actual value of x will depend on the weight, which is equal to the force.
x = F/k
Divide force by k. You will get the value of x in meter. Multiply it by 100 to get the value of x in cm

Do you know how to do the second one?
