Homework Statement
A 5 kg object is pushed up along a plane inclined 30 degrees from the horizontal by a force of 20.25 N. If the velocity is 2.0 m/s at the foot of the plane and the coefficient of kinetic friction between the plane and the object is 0.25, how far up the plane will the object go?
Homework Equations
f = uN
The Attempt at a Solution
f = uN
f = (0.25)(20.25 N)
f = 5.0625 N
I really don't know how to continue the solution. Do I need to use trigonometry here? I think gravity will cause the moving object to decelerate and stop at some point when it goes up. I just don't know what formulas and equations to use before I can arrive at the solution. Thanks in advance.
