One end of an ideal massless string is attached to a box of mass M which is free to slide along a frictionless surface which is inclined at an angle ? above the horizontal. The string is parallel to the inclined surface until it passes over an ideal pulley. The other end of the string is attached to a second box, also with mass M, which is freely suspended.

\f- a 9% Part to) Please use the interactive area below to draw the best Free Body Diagram to represent the forces on the suspended box. - A 9% Part (D) Please use the interactive area below to draw the best Free Bod}.r Diagram to represent the forces on the box which is sliding on the frictionless inclined surface. T 5 9% Part to) Two coordinate systems have been added to the diagram for the problem. For the suspended block we will use the horizontal-vertical, x-y coordinates. For the block on the incline we will use the rotated, x'-y' coordinates. Enter an expression for the net force in the vertical direction for the suspended block using the x-y coordinates. - EL 9% Part ((1) Using the x'-y' coordinates, enter an expression for the component of net force parallel to the inclined surface for the block that is sliding along that surface. Refer to the gure in the previous step for an illustration of the coordinate axes. ; 3 9% Part to) Enter an expression for the vertical acceleration of the suspended block, yuspcndcd' aylsusmm = FT - M g X .-\\1lcrnpl.l
