A mass of 2.00 kg rests on a rough horizontal table. The maximum frictional force between the mass and the table is 12n. The block is attached to a hanging mass by a string that goes over a smooth pulley. What is the largest mass that can hang in this way without forcing the block to slide?

Answer:
1.2kg
Explanation:
We know that u = fn where u is the firction force. fn would be normal force * 0.60
To calculate the normal force we multiply 2 by 9.81 which gives us 19.62. Then we multiply that by the coefficient of friction which is 0.60
0.60 x 19.62 = 11.72 N
We need the mass of the block so we divide that by 9.81 which gives us 1.2kg
We can also not calculate the normal force and times 0.60 by 2 which gives us the answer to shorten our answer but it won't be as clear.
