The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m = 12.5 kg is on a horizontal table and the other block with mass m = 9.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. m -x m2 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. Your answer should involve the tension, T. a Tim Correct! 25% Part (b) Under the same assumptions, write an expression for the acceleration, a, the block of mass my experiences in the y-direction. Your answer should be in terms of the tension, I and m. a2 m2-T/m2 X Attempts Remain Feedback: is available. 25% Part (c) Carefully consider how the accelerations a and a are related.
