  1. Question 1

    Q1. A body is rotating with an angular velocity of 4 rad/s. If the radius is 2 m, find its centripetal acceleration.

    • A) 16 m/s²
    • B) 32 m/s²
    • C) 40 m/s²
    • D) 64 m/s²

    Answer: 32 m/s²

    Explanation: Centripetal acceleration is given by a = ω² * r = (4)² * 2 = 32 m/s².
