Two blocks of masses 20 kg and 8.0 kg are connected together by a light string and rest on a frictionless, level surface. Attached to the 8.0-kg mass is a second light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 1.0 m/s2, what is the tension in the second string attached to the 8.0-kg mass?
 a. 14 N
  c. 28 N
  b. 6.0 N
  d. 4.0 N

Question 2

Two blocks of masses 20 kg and 8.0 kg are connected together by a light string and rest on a frictionless, level surface.

 a. 14 N
  c. 10 N
  b. 6.0 N
