A 5.0 box is on a frictionless 45 slope and is connected via a massless string over a massless, frictionless pulley to a hanging 1.7 weight.
a) What is the tension in the string if the 5.0 box is held in place, so that it cannot move?
b) If the box is then released, which way will it move on the slope ( Downward or Upward)?
c) What is the tension in the string once the box begins to move?
