  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 block of mass 9.1 kg rests on a horizontal frictionless floor, and is connected to a vertical wall by a spring of force constant 205 N/mN/m as shown in the figure. When the spring is in its equilibrium position (neither stretched nor compressed), the block just touches a second lighter block of mass 3.4 kg at rest on the frictionless floor. The spring is now compressed by 0.12 mm (only the heavier mass is moved towards the wall) and...
