Two blocks connected by a string are pulled across a horizontal surface by a force applied to one of the blocks, as shown. The coefficient of kinetic friction between the blocks and the surface is 0.25. If each block has an acceleration of 2.0 m/s2 to the right, what is the magnitude F of the applied force?
 
 
 
   
  a.
  25 N
   
  b.
  18 N
   
  c.
  11 N
   
  d.
  14 N
   
  e.
  7.0 N

Question 2

Two blocks are accelerated across a horizontal frictionless surface as shown. Frictional forces keep the two blocks from sliding relative to each other, and the two move with the same acceleration. If F = 1.2 N and M = 1.0 kg, what is the horizontal component (frictional force) of the force of the small block on the large block?
 
   


   
  a.
  0.48 N to the right
   
  b.
  0.72 N to the right
   
  c.
  0.72 N to the left
   
  d.
  0.48 N to the left
   
  e.
  0.65 N to the left
