Question

17. Frictional Forces and Newton's 2"d Law In each of the situations described, determine the direction of the frictional force (or state that it is zero) and explain your reasoning. If the given information is insufficient to determine the direction of the frictional force, explain why. Also state whether the frictional force is static or kinetic. a. A child slides down a slide in a playground. The frictional force on the child is b. A woman stands on an airport's moving sidewalk and moves at constant velocity. The frictional force on the woman is c. A toolbox sits in the bed of a truck that is initially stopped at an intersection. The truck darts forward and the box starts to slide toward the back of the truck. The frictional force on the toolbox while it is sliding is d. A toolbox sits in the bed of a truck that is initially stopped at an intersection. The truck darts forward and the box starts to slide toward the back of the truck. The frictional force on the bed of the truck due to the toolbox while the toolbox is sliding is
