Projectile Motion – PHY 141/161
Introduction and Questions: Measure kinematic quantities for a ball launched
horizontally from a tabletop by a spring-loaded device. Use these to calculate the
initial speed of the ball. Predict the range and maximum height of the ball’s
trajectory, when launched at an upward angle, and verify experimentally. Answer
the following questions.
1. What is the initial speed of the ball?
xxx
2. Overall, are the maximum height predictions accurate?
xxx
3. Overall, are the range predictions accurate?
xxx
4. What is the nature of the differences between the predictions and the
experimental results? Are these random or systematic?

Data & Analysis: See Table 1 (horizontal launch), Table 2 & Graph (upward angle
launches).
