The coefficient of static friction between hard rubber and normal street pavement is about 0.90. On how steep a hill (maximum angle) can you leave a car parked?

First thing to do is to draw the system described above. Then, write an equation for the forces present.

ΣF = Fg - Ff
0 = mgsin∅ - umgcos∅0 = gsin∅ - ugcos∅
u = tan∅
∅(max) = tan^-1 (u)

The static friction is thus the friction that is seen in a solid object that prevents them from moving or sliding down. Thus  the force of equation for the force that is present. ΣF = Fg - Ff.

What is coefficient of the static friction ?

The static friction will be higher than the coefficient of the kinetic friction. Thus can be shown by the 0 = mgsin∅ - umgcos∅0 = gsin∅ - ugcos∅ u = tan∅ , ∅(max) = tan^-1 (u). Thus will considered to be arise if the surface is rough enough to make the friction. Will maximum the contact area.
