Problems 43 describe a situation. For each, draw a motion diagram, a force-identification diagram, and a free-body diagram.
A rocket is being launched straight up. Air resistance is not negligible.
The motion diagram states the velocity of the ball throughout the motion.
The force arises due to the air resistance and gravity.
The rocket is accelerating upward.
There are three forces acting on the rocket:
Problems 35 through 40 show a free-body diagram. For each:
a. Identify the direction of the acceleration vector and show it as a vector next to your diagram. Or, if appropriate, write b. If possible, identify the direction of the velocity vector 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.
