• A block is pushed across a flat surface at a constant speed

• A block slides down a ramp at a constant speed

• A Three way tug of war between David, Sarah And James

• A 200kg block is pushed across a level surface whose coefficient of friction is 0.6Find the Force of the push

• The Normal Force always acts perpendicular to the surface

• The frictional force always acts parallel to the surface

• Gravity always act straight down

Θ

• When drawn this way, the Normal Force and Frictional Force must be broken into components

• Fnx = Ffx

• Fny + Ffy = Fg

• By changing the orientation of the ramp, the problem is much simplified.

• Fgx = Ff

• Fgy = Fn

• Find the coefficient of friction
