A car is moving on a circular track with a radius of 50 m. If its speed is 20 m/s, find its centripetal acceleration.
Q1. A car is moving on a circular track with a radius of 50 m. If its speed is 20 m/s, find its centripetal acceleration.
Answer: 8 m/s²
Explanation: Centripetal acceleration = v² / r = (20)² / 50 = 8 m/s², using a = v² / r formula.
