Lab Section: ______ Name: ______________________________ Lab Instructor: ______________________________ Grade: ______ P1112 Lab Notes Pre-lab 5-1 Cornell University, Spring 2009 Lab Unit # 5 Pre-lab Questions: Ideal & Non-ideal Projectiles 1. In point form give an outline of the tasks you will perform for each component of the lab. There is no unique answer to this task , and the degree of detail is largely up to you. Any reasonable answer should get full points . You should aim to have no more than 3 points for each category. Focus on what are the key tasks. (a) Acquiring data for an ideal projectile. (b) Analyzing data for an ideal projectile. (c) Acquiring data for a non-ideal projectile. (d) Analyzing data for a non-ideal projectile. (e) Cleaning up.

Unformatted text preview: indicated by the vector shown to the right. Draw a free-body diagram for the projectile at this instant, including all forces that might possibly be relevant. Clearly label all of the forces in your diagram and indicate the cause of each force. 3. How is the magnitude of the drag force on a projectile expected to relate to its speed? 4. How is the direction of the drag force on a projectile expected to relate to its velocity? 5. For a given launch speed, at what angle from the horizontal should an ideal projectile be launched in order to maximize its range, assuming that it is launched from, and lands at, the same height? 6. For a non-ideal projectile launched at the same speed, should this launch angle be larger, smaller, or remain the same in order to maximize the range? Please explain your reasoning. v r...
