SUMMARY
The problem involves calculating the horizontal speed of a ball bearing launched from a slingshot, aimed at a target 78 meters away. The time taken for the sound of impact to reach the shooter is 0.7 seconds, and the speed of sound is given as 330 m/s. To determine the speed of the ball bearing, the formula v_x = distance/time is applied, leading to the conclusion that the ball bearing must travel at approximately 114.3 m/s to reach the target in the specified time.
