Homework Statement
A block of mass "m" slides at constant speed down a uniform plane inclined at an angle "degrees symbol" to the horizontal, as shown.
- Shows an incline with a block on top, like this: "<" with a block on top.
1. On the diagram, sketch and label appropriate arrows to represent the three forces acting on the black: friction, the normal force, and the force of gravity.
2.
Express the component of the block's weight parallel to the incline "F" (parallel symbol) and the component of the block's weight perpendicular to the incline "F" (perpendicular symbol) in the terms of "F"(small g on the bottom of F).
3. Show µ = tan (angle symbol)
Homework Equations
The Attempt at a Solution
I only kinda understood the first question. I am pretty sure that friction arrow will be from downward to up, when the block is sliding down, opposite of the way the block is going. Gravity arrow will be from top, since gravity pushes down from there.
I am not sure where the normal force will be though.
Thanks
