A crate of mass 250kg rests in equilibrium on a slope inclined at 20 degrees to the horizontal.
i) Find the frictional force acting on the crate.
ii) Given that the equilibrium is limiting, calculate the coefficient of friction between the crate and the slope.
iii) The crate is now pushed horizontally with a force of magnitude 2000N. (There is a diagram here which just shows the arrow pointing towards the slope with 2000N written by it).
Please can you explain how to do these? Thanks
