8. A box with mass 10 kg is sitting at rest on a horizontal floor. At time t = 0, an attached rope begins pulling the box along the floor. There is kinetic friction between the box and the floor with ug = 0.16. After the box has been pulled 2.2 meters, the system is moving at 1.5 m/s. (a) How much total work has been done on the box? (b) What is the tension in the rope?

**Physics Problem**

A box with mass 10 kg is sitting at rest on a horizontal floor. At time \( t = 0 \), an attached rope begins pulling the box along the floor. There is kinetic friction between the box and the floor with \( \mu_k = 0.16 \). After the box has been pulled 2.2 meters, the system is moving at 1.5 m/s.

**Questions:**

(a) How much total work has been done on the box?  
(b) What is the tension in the rope?
