A box is pulled across a bench. Four forces are applied to the box. The box moves a distance 0.8 m as shown. Determine the work done by each force.

• A. W_A = -56 J
  W_B = -32 J
  W_C = 104 J
  W_G = 0 J
• B. W_A = 56 J
  W_B = 32 J
  W_C = 104 J
  W_G = 0 J
• C. W_A = -56 J
  W_B = -32 J
  W_C = 104 J
  W_G = 48 J
• D. W_A = 56 J
  W_B = 32 J
  W_C = - 104 J
  W_G = - 48 J

Answer: (A)
