Homework Statement
A man with a mass of 65kg is traveling in an elevator and stands on a set of scales, at a given instant the scales measure his weight to be 72kg, find the acceleration of the equation
Homework Equations
f=ma
w=mg
FN =mg+ma[/B]
The Attempt at a Solution
[/B]
I know that the weight with gravity is 65kg and then changes to 72kg when he gets into the elevator because the elevator is pushing back onto him. I also know the elevator is going UP because of the positive change in weight.
Fn = 65kg + 72kg
Fn = 137kg
How do I find the acceleration?
