A 10-1b block of steel is at rest on a horizontal table. The coefficient of static
friction between block and table is 0.50.
(a) What is the magnitude of the horizontal force that will just start the block moving?
(b) What is the magnitude of a force acting upward 60° from the horizontal that will just start the block moving?
(c) If the force acts down at 60° from the horizontal, how large can it be without causing the
block to move?
Please provide the image with full explanation.
