A car is moving in a circular path with a radius of 100 m. If the speed is 20 m/s, find the centripetal acceleration.
Q1. A car is moving in a circular path with a radius of 100 m. If the speed is 20 m/s, find the centripetal acceleration.
Answer: 4 m/s²
Explanation: Centripetal acceleration is given by a = v² / r = 20² / 100 = 400 / 100 = 4 m/s².
