Unformatted text preview: Understand projectile motion. Know to calculate major parameters of its motion. For example: How long it takes to get to top of trajectory, the range at a given angle, the maximum height at a given initial velocity, etc. 11) Be able to perform variations of the homework problems. Examples of Problem Variations. Problem 2.44 (Original) It is possible to shoot an arrow at a speed as high as 100 m/s. If friction is neglected, how high would an arrow launched at this speed rise if shot straight up? Problem 2.44 (Variation 1) It is possible to shoot an arrow at a high speed. If friction is neglected, at what speed would an arrow need to be shot straight up if it rises to 500 m? Problem 2.44 (Variation 2) You observe an arrow is shot straight up at a speed of 100 m/s and that it rises to 350 m. If friction is neglected, is the measured height consistent with the initial launch speed? 12) Do more problems than were assigned you need practice....
