Randall D. Knight — Force and Motion: Problem 36

Problems 35 through 40 show a free-body diagram. For each: a. Identify the direction of the acceleration vector \(\vec{a}\) and show it as a vector next to your diagram. Or, if appropriate, write \(\vec{a} = \vec{0}\). b. If possible, identify the direction of the velocity vector \(\vec{v}\) and show it as a labeled vector. c. Write a short description of a real object for which this is the correct free-body diagram. Use Examples 5.4, 5.5, and 5.6 as models of what a description should be like.
