Question

Two blocks are connected by a massless string that doesn’t stretch.  One block with mass (= 10kg) is over a frictionless inclined surface attached by a massless friction less pulley to a free hanging block with a mass(= 5kg). The inclined plane is at an angle 10° above the horizontal.  Draw a free body diagram for both blocks and then answer the questions below.  Show all work.  Assume acceleration due to gravity is 10 .

  1. What is the normal force of the free hanging block?
  2. What is the Tension force of the inclined block?
  3. What is the acceleration of the free hanging block?

 

 

  1. At the original masses of the blocks and the same incline, how much friction force would you need to keep the objects in equilibrium?
  2. At the original masses of the blocks with no friction on the incline, at what angle of the incline would you need to keep the blocks in equilibrium?
  3. At the original angle of incline with no friction, and mass of the hanging block is the same (= 5kg) what would the mass of the block on the surface need to be to keep the 2 blocks in equilibrium (= ?kg)
