Homework Statement
A 10.0-kg mass is placed on a 25.0o degree incline and friction keeps it from sliding. The
coefficient of static friction in this case is 0.580, and the coefficient of sliding friction is
0.520. The mass is given a shove causing it to slide down the incline.
Homework Equations
What is the frictional
force while the mass is sliding?
The Attempt at a Solution
This is all I have so far, but I don't exactly understand it:
Frictional force while the mass is sliding = μmgcosθ = 0.52 X 10 X 9.8 X cos 25
= 46.19 N
I need a full step-by-step explanation, if possible. I'll also take any other information about the problem that may make it easier. Thank you.
