1. The problem statement, all variables and given/known data A mass(A) of 12kg is on a slope with an angle of 30 degrees. The static coefficient of friction of the slope = 0.5 (μs) The kinetic coefficient of friction 0.3 The length of the slope from the block= 5m However the The mass(A) is connected to another mass(B) which is hanging over the edge. Q. What is the maximum mass (B) can be before mass (A) will begin to move. 2. Relevant equations M(B) ≤ μsM(A) 3. The attempt at a solution I just subbed into this 0.5 x 12 = 6 Kg but my teacher marked it wrong on the test. Is it possible the fact its on a slope will have anything to do with it so do I use the angle in some way?
