A particle is moving in a circular path of radius 2 m with a constant speed of 4 m/s. What is its centripetal acceleration?
Q1. A particle is moving in a circular path of radius 2 m with a constant speed of 4 m/s. What is its centripetal acceleration?
Answer: 8 m/s²
Explanation: Centripetal acceleration = v² / r = (4)² / 2 = 8 m/s², using the formula for centripetal acceleration.
