SUMMARY
The problem involves calculating the speed of a ball bearing launched from a slingshot, aimed at a target 78 meters away. The total time from launch to hearing the impact is 0.7 seconds, with the speed of sound at 330 m/s. To find the speed of the ball bearing, one must account for the time it takes for sound to travel back after the impact. The calculation reveals that the ball bearing must travel at approximately 210 m/s to reach the target in the given timeframe.
