Homework Statement
So a hot wheel was put on a linear track, and one end of the track is slowly lifted until the cart starts to move. The height of the one end is measured as 6.45cm and distance (or hypotenuse) is 189.5cm
mass of hot wheel is 45.7 g
Homework Equations
PE = mgh
KE = 1/2mv2
Wf = Ffd
Ff = μmg
The Attempt at a Solution
So I was thinking of using PE = KE + Wf, but the car doesn't move, so I can't have KE in there. If that's the case, do I just set up the equation as PE = Wf ? and find the coefficient of static friction from there?
