The 65 kg man climbs up the rope with an acceleration of 0.25 m/s^2, measured relative to the rope. Determine the acceleration of the 80 kg block. This is just a man climbing up a rope on the right with the rope wrapped over a pulley and on the other side a block hangs. ok so the two equations I came up with from the FBD's are T-784.8 = 80 * (accel. of block) T - 637.65 = 65 * (accel. of man) An assumption I made is the accel. of block and accel of rope must be the same. Ok so the acceleration of the man with respect to the rope = 0.25? How can I use this piece of information to determine the acceleration of the block.
