A Physics "Problem" [SOLVED]

[ViBeZ]

"A spring with a spring constant of 300N/m (Newtons per meter) is designed to hold masses up to 225kg. What is the maximum displacement,  h, needed by the spring if loaded to full capacity? "

Spoiler (click to show)

Alright so I was suspended for 3 days and I lost 182 Minutes worth of Physics and we had a test funny enough some of my friends didn't blew past more like they couldn't and I felt really upset because they were here but couldn't Crack down any of the problems none of them and I couldn't Crack a True or False statement so yea let's end that.

My Problem is I want to know what equation to do for this since I never ran into "h" so yea to sum it up, how do I get "h" what steps and or equations do I need to get it?

h = x, y or even d in some textbooks. Use Hooke's law.

So "h=x" then "F=k×X" and then that's my "h"? Also do you know the SI unit for "h"?

h is the displacement, aka "x", measured in meters.

It's the meter, but you should infer your units/dimensionals from the info you're given in the problem; in this case the spring constant is in N/m, the mass is in Kg (and thus the weight is in N) so your distance should be in meters. N/cm aren't unheard of, nor are KN/m, nor N/mm, etc.

Am I hot yet?

[Foobs]

It's all wrong :/

F should be 225 times g, k is your spring constant and x, regardless of its magnitude, should be in meters or centimeters, not N/m. It's a linear distance, not force per distance.

You got it.

I'm on Fire, thank you Fubini and Danny

I know the feelin' you're welcome.
