A body is moving in a circular path with a constant speed. If its centripetal acceleration is 9 m/s² and radius is 3 m, what is its speed?
Q1. A body is moving in a circular path with a constant speed. If its centripetal acceleration is 9 m/s² and radius is 3 m, what is its speed?
Answer: 3 m/s
Explanation: Centripetal acceleration (a_c) is given by v²/r. So, v = √(a_c * r) = √(9 * 3) = √27 = 3√3 m/s, no, it is √(9*3) = √27 m/s.
