The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1 = 12.5 kg is on a horizontal table and the other block with mass my = 7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. m m, Otheexpertta.com 25% Part (a) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass my experiences in the x-direction.
