Homework Statement


Calculate the acceleration and the tension in the rope. For your variables use "m1", "m2", "theta1", "theta2" and "g". Assume all surfaces are frictionless, and the pulley and rope are massless and frictionless.

once you know the acceleration,
the Tension can be obtained by isolating
*either one* of the blocks
... "cutting the rope" allows T to be measured.

Try to draw the FBD of the two blocks.

Now as the surfaces are friction less

T - m1gsin(theta1) = m1a

and m2gsin(theta2) - T = m2a

are you aware that there is an arrow in fed ex? and y dont you try solving it in terms of force parallel? its much easier
