Unformatted text preview: reddy (ar38357) Projectile Motion clancy (SCI411-2) 1 This print-out should have 6 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points A bowling ball accidentally falls out of the cargo bay of an airliner as it flies along in a horizontal direction. X W U V Z Y As observed by a person standing on the ground and viewing the plane as in the fig- ure, which path would the bowling ball most closely follow after leaving the airplane? 1. Z 2. Y 3. V correct 4. X 5. U 6. W Explanation: The horizontal direction of ball motion is due to initial velocity it got from the air- liner, and the vertical is due to gravity. The resultant motion is on a parabolic curve dotted curve V (example of projectile mo- tion). Note: Dotted curves X and Z are arcs of circles. Dotted line U is a straight line. Dot- ted curve Y is a bezier curve. Dotted curve W is a parabolic curve with axes inverted....
