The coefficient of static friction between a block of mass m and an incline is = 0:3. (a) What can be the maximum angle e of the incline with the horizontal so that the block does not slip on the plane ? (b) If the incline makes an angle 8/2 with the horizontal, find the frictional force on the block.
