A car is moving on a circular track. If its speed is 30 m/s and radius is 90 m, find its centripetal acceleration.
Q1. A car is moving on a circular track. If its speed is 30 m/s and radius is 90 m, find its centripetal acceleration.
Answer: 10 m/s²
Explanation: Centripetal acceleration = v² / r = (30)² / 90 = 10 m/s², using a = v² / r formula.
