I have this very confusing two part question that i am having trouble understanding.
For the first question i first created a free body diagram to show the forces acting on both the boxes.
However i am unsure of what to do after this since i don't understand how to use newtons second law to find acceleration for this acceleration.
From what i think i understand you need to sum all of newtons forces on the first box and get t on one side of the equation then plug in t for the equation for the sum of the forces on the second box and then get a (acceleration) by itself. but i am not sure how to do this.
the second part (b) is also confusing since i don't understand the first part of this question.
below is the questions a and b.
two blocks are connected by a string that passes over a friction less pulley. mass m1 sits on a plane inclined to and angle of 30 degrees above the horizontal and mass m2 hangs freely over the edge of the inclined plane.
a)assuming the plane is frictionless determine the acceleration of the system in terms of the masses and the angle of the plane
b) if m=m2=10kg determine the coefficient of friction necessary to keep the masses stationary.
