SUMMARY
The discussion focuses on calculating centripetal acceleration and net horizontal force for a child on a merry-go-round. Using the formula for centripetal acceleration, the child’s acceleration is determined to be 0.29 m/s² with a mass of 25 kg and a radius of 7.8 m. The net horizontal force exerted on the child is calculated using the formula Fc = mv²/r, resulting in a force of 7.21 x 10^4 N. These calculations demonstrate the application of fundamental physics equations in real-world scenarios.
