  1. Question 1

    Q1. A body is rotating with an angular velocity of 5 rad/s. If the radius is 3 m, find its centripetal acceleration.

    • A) 50 m/s²
    • B) 60 m/s²
    • C) 75 m/s²
    • D) 90 m/s²

    Answer: 75 m/s²

    Explanation: Centripetal acceleration is given by a = ω² * r = (5)² * 3 = 75 m/s².
