SUMMARY
The discussion centers on the motion of a steel ball rolling down one slope and up another, with specific focus on calculating acceleration and time. The ball takes 2.5 seconds to reach a speed of 5.0 m/s at the bottom of the first slope, allowing for the calculation of acceleration using the formula v = at, resulting in an acceleration of 2.0 m/s². Given that the acceleration on the second slope is half that of the first, the ball's deceleration on the second slope is 1.0 m/s². Consequently, it will take 5.0 seconds for the ball to come to a complete stop on the second slope.
