  1. A 8.0kg block is pulled along a horizontal frictionless floor by a cord that  exerts a force T​ ​ = 10N at an angle of 30​o above the horizontal as shown  below. Draw a free body diagram for each scenario below.

   

  1. What is the acceleration of the block? Include FBD
  2. The force T​ ​ is slowly increased. What is the value of T​ ​ just before the block is lifted off the floor? Include FBD
  3. What is the acceleration of the block just before it is lifted off the floor? Include FBD

A mass m = 13 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.07, for a distance d = 5.1 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 33° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 33° (thus on the incline it is...
