Two blocks (one of which is on a ramp) are attached via a string looped over a pulley. The block on the incline has a mass of 5.0 kg; the block hanging downward (suspended by the pulley) has a mass of 7.0 kg. Assume the usual things (non-stretchy massless string, frictionless lightweight pully, air resistance / friction is negligible, etc.) What angle of incline (measured against the horizontal) allows the blocks to have constant velocity?
