The shower curtain rod in Figure P6.7 is called a tension rod. The rod is not attached to the wall with screws, nails, or glue, but is pressed into the wall instead. Explain why the rod remains at rest, supporting the curtain. Explain why the name is misleading and come up with a better name. FIGURE P6.7

A sled and rider have a total mass of 56.8 kg. They are on a snowy hill. The coefficient of kinetic friction between the sled and the snow is 0.195. The angle of the hills slope measured upward from the horizontal is 19.5. What is the acceleration of the rider? Is the acceleration greater, less than, or equal to your result if a more massive rider uses the same sled on the same hill? Explain.

You blow a small piece of paper through the air. Is the force on the paper a contact force or a field force? Explain.
In many textbook problems, we ignore certain complications such as friction and drag. The problems contain key words that indicate such a simplification is being used. For example, if a surface is described as slippery, it means that we can ignore friction. Look at the previous chapters problem sets. Find five uses of these key words and explain how to interpret each case.
