Question
### Speedometer Readings of a Ball Launched Upward

A ball is equipped with a speedometer and is launched straight upward. The speedometer reading three seconds after launch is shown at the right; the ball is moving upward. At what approximate times would the ball display the following speedometer readings?

#### Speedometer Readings:

1. **Initial Speedometer Reading**:
   - *Description*: The needle points to 40 m/s.
   - *Graph Details*: The speedometer displays a gauge ranging from 0 to 60 m/s, with increments of 10. The needle is positioned at 40 m/s.

2. **Unknown Speedometer Reading 1**:
   - *Description*: The needle points to 0 m/s.
   - *Graph Details*: The speedometer displays the same gauge with the needle at 0 m/s, indicating the ball has no upward speed.

3. **Unknown Speedometer Reading 2**:
   - *Description*: The needle points to 30 m/s.
   - *Graph Details*: The speedometer again displays the same gauge, with the needle positioned at 30 m/s.

Users are prompted to approximate the times when these speedometer readings might be displayed, with the initial setting showing a time of 0 seconds. There is an option to "Check Answer" at the bottom.

This exercise is designed to help students understand concepts of velocity, time, and acceleration in a projectile motion context, encouraging them to think critically about the motion and forces acting on the ball.
