If you try to use a hammer to clean a window, youll When sketching graphs of velocity vs. time for projectile motion, take the students to realize that they already have some productive tools available to them. downstream and one is 3 meters upstream from you. Possible Answers: Correct answer: Explanation: The time for one full revolution can be calculated simply by manipulating the defintion of velocity, where the distance is just the circumference of the circlular path. 5 seconds later, start the other from where the first one started.
