If the acceleration of a system is zero, are no external forces acting on it? What about internal forces? Explain your answers.
What force is exerted on the tooth in Figure 4.38 if the tension in the wire is 25.0 N? Note that the force applied to the tooth is smaller than the tension in the wire, but this is necessitated by practical considerations of how force can be applied in the mouth. Explicitly show how you follow steps in the Problem-Solving Strategy for Newton's laws of motion. Figure 4.38 Braces are used to apply forces to teeth to realign them. Shown in this figure are the tensions applied by the wire to the protruding tooth. The total force applied to the tooth by the wire, Fapp, points straight toward the back of the mouth.

Suppose two children push horizontally, but in exactly opposite directions, on a third child in a sled. The first child exerts a force of 71 N, the second a force of 98 N, kinetic friction is 4.5 N, and the mass of the third child plus sled is 23 kg. Using a coordinate system where the second child is pushing in the positive direction, calculate the acceleration in m/s2.
