1. The problem statement, all variables and given/known data Two blocks are connected by a string that goes over an ideal pulley as shown in the figure and pulls on block A parallel to the surface of the plane. Block A has a mass of 3.00 kg and can slide along a rough plane inclined 30.0° to the horizontal. The coefficient of static friction between block A and the plane is 0.400. What mass should block B have in order to start block A sliding up the plane? 2. Relevant equations box A- sum of x & sum of y box B- sum of y plug into each other 3. The attempt at a solution m2=(ms*m1*sin(theta)+m1*cos(theta) =3.198 Thanks.
