Two blocks, joined by a string, have masses of 3.0 and 4.0 kg. They rest on a frictionless horizontal surface. A second string, attached only to the 4.0-kg block, has horizontal force = 40 N applied to it. Both blocks accelerate. Find the tension in the string between the blocks.
 a. 23 N
  b. 5.7 N
  c. 17 N
  d. 93 N
  e. 120 N

Question 2

A box slides up an incline with an angle of elevation . When the box reaches its maximum distance up the incline it stops and does not slide down the incline due to friction. What is the minimum value of the coefficient of static friction for this to occur?
 a. s = tan b. s = sin
  c. s = cos d. s = 1
