Question

What is the force applied by a spring as it stretches upward 0.25 meters and has a k value of 25 newtons per meter?

Answer 1

F = - k x and you have k and you have x

Answer 2

I did this -(25)(.25) and got -6.25 but that's not one of the answer choices.

Answer 3

A word to the wise -
Consider finding (only) magnitude via mathematics and use physics to find the sign.

Answer 4

sign is often rather arbitrary, too

Answer 5

I wont agree to that ^^

Answer 6

We have the Earth and the moon. In which direction is distance positive?

Answer 7
