object's drag balances itš welght. A particular
object weighs 250 N and its terminal velocity is
50. m/s. What is the force of drag on it when it is
falling at 50. m/s? When it is falling at 25 m/s?
2. Often, a "wing" curved upward and backward
will be mounted on the rear of a racecar. What is
the purpose of such a wing?
3. Would an airbrush work if the airflow channel
widened as it reached the tube leading to the
paint reservoir? Why or why not?
