Chapter 5, Problem 78PQ
Two children, Raffi and John, sitting on sleds tied together with a massless rope, are being dragged across a frozen river by their playful Siberian husky Rex who is supplying a 112-N horizontal force (Fig. P5.78). The coefficient of friction between the sleds and the ice is 0.08, the combined mass of Raffi and his sled is 42.0 kg, and the combined mass of John and his sled is 51.0 kg.
- a. Draw a free-body diagram for each of the child–sled systems.
- b. What is the acceleration of the system?
- c. What is the tension FT in the rope connecting the two sleds?
