PHYSICS 5A Lecture Notes - Lecture 6: Paralympic Games, Circular Motion
Document Summary
Physics 5a_ lecture 6_ circular motion and 2d projectile motion. Do not spend too much time on concept question. Using these equations, you can eliminate t and show that the object"s trajectory is a parabola. R= range of trajectory (how far in x the object travels) = angle between object"s initial velocity and x axis. You use these questions to find the highest point that the object reaches when it is being launched into the air. First you would need to find the time at the point and then plug into the second question, to find height at point y. Range: by symmetry, the time for the object to come back to the ground is t o . Putting that time into the position equation in x gives: Ex: flame lighting at barcelona olympics games. At the summer olympic games in barcelona, the olympic cauldron was lit by a flaming arrow shot by paralympian antonio rebollo.
