SUMMARY
The discussion centers on calculating the acceleration and displacement of a ball rolling up and down a hill. The ball starts with an initial velocity of 4.00 m/s and, after 5 seconds, rolls down at 6.0 m/s. The acceleration can be determined using the change in velocity over time, while the displacement requires considering the initial velocity and the time of travel. The assumption of a constant hill angle allows for the application of gravitational components in the calculations.
PREREQUISITES
