I need help with options C to D please

(5%) Problem 16: Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass my = 14 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, 7. Use the coordinate system specified in the diagram. m -x my Otheexpertta.com A 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, I. A 25% Part (b) Under the same assumptions, write an expression for the acceleration, a2, the block of mass my experiences in the y-direction. Your answer should be in terms of the tension, I and my. A 25% Part (c) Carefully consider how the accelerations a, and a2 are related. Solve for the magnitude of the acceleration, a1; of the block of mass m1, in meters per square second. A 25% Part (d) Find the magnitude of the tension in the rope, T, in newtons.
