A particle is moving in a circular path. If its speed is 8 m/s and radius is 4 m, what is its centripetal acceleration?
Q1. A particle is moving in a circular path. If its speed is 8 m/s and radius is 4 m, what is its centripetal acceleration?
Answer: 16 m/s²
Explanation: Centripetal acceleration (a_c) = v² / r = (8)² / 4 = 16 m/s², using the formula a_c = v² / r.
