A car is moving on a circular track of radius 200 m with a speed of 30 m/s. What is its centripetal acceleration?
Q1. A car is moving on a circular track of radius 200 m with a speed of 30 m/s. What is its centripetal acceleration?
Answer: 4.5 m/s²
Explanation: Centripetal acceleration (a) = v² / r = (30)² / 200 = 4.5 m/s², using the formula a = v² / r.
