The three blocks shown are released from rest and are observed to move with accelerations that have a magnitude of 1.5 m/s². What is the magnitude of the friction force on the block that slides horizontally? Disregard any pulley mass or friction in the pulley and let M = 2.0 kg.
 
   

   
  a.
  6.0 N
   
  b.
  5.1 N
   
  c.
  5.5 N
   
  d.
  4.6 N
   
  e.
  3.7 N

Question 2

In the figure shown, the coefficient of kinetic friction between the block and the incline is 0.40. What is the magnitude of the acceleration of the suspended block as it falls? Disregard any pulley mass or friction in the pulley.
 
   

   
  a.
  3.4 m/s²
   
  b.
  3.7 m/s²
   
  c.
  4.2 m/s²
   
  d.
  3.9 m/s²
   
  e.
  5.4 m/s²
