A 17 kg block is at rest on an incline with angle 33. The coefficients of static and kinetic friction are 0.7 and0 0.59, respectively. The acceleration of gravity is 9.8m/s^2.
1) What is the frictional force actin on the 17kg mass?
2) What is the larges angle the incline can have so that the mass does not slide down the incline?
for 1, I thought Ff was just the coefficient of static friction (0.7) times the normal force, but that apparently isn't right.
for 2, I don't have a clue...
