### Educational Analysis of Projectile Motion with Speedometer Readings**Problem Statement:**A ball is equipped with a speedometer and launched straight upward. The speedometer reading two seconds after launch is shown on the right; the ball is moving upward. At what approximate times would the ball be moving downward and display the following speedometer readings?**Diagrams and Readings:**1. **Speedometer at Two Seconds:** - The first diagram shows a speedometer reading of 20 meters per second (m/s).2. **Subsequent Speedometer Readings:** - **Speedometer showing 10 m/s:** - This is likely intended to represent a downward motion of the ball at a speed of 10 m/s. - **Time (s):** Placeholder text indicates "Tap to Answer" for determining when this speed is reached on the way down. - **Speedometer showing 20 m/s:** - This appears similar to the initial reading, suggesting it represents the ball on its downward trajectory reaching the same speed. - **Time (s):** Placeholder text says "Tap to Answer" for indicating when this speed is achieved again during descent.**Conceptual Understanding:**The problem involves understanding the motion of a projectile under gravity. Initially, the ball is moving upward, and gravity slows it until it stops momentarily at its peak, then it accelerates downward. The speedometer readings on descent mirror those during ascent but in reverse order as the same speeds are reached moving back downward.This exercise helps in understanding concepts of acceleration due to gravity, symmetry in projectile motion, and the relationship between speed and time in vertical motion.
