In the figure, two blocks are shown with an inclined plane. The two blocks are connected by a massless string strung over a massless pulley. The mass of Block #1 is 3.57 kg and that of Block #2 is 11.0 kg. The angle θ of the incline is 43.0 degrees. The plane is NOT smooth and has a coefficient of static friction of 0.570 and a coefficient of kinetic friction of 0.240.
Taking the positive direction to be up the incline, determine the following:
(a) the acceleration of Block #1 if it is initially at
(b) the acceleration of Block #1 if it is already moving up the plane.
(c) the acceleration of Block #1 if it is already moving down the plane.
