  • Two blocks are connected by a massless rope.

    Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1=13.75 kg is on a horizontal table and the other block with mass m2=6.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. Part (a) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass...
