  1. Question 1

    Q1. A wheel is rotating at an angular velocity of 4 rad/s. If its radius is 0.5 m, what is the linear velocity of a point on its rim?

    • A) 1 m/s
    • B) 2 m/s
    • C) 3 m/s
    • D) 4 m/s

    Answer: 2 m/s

    Explanation: Linear velocity (v) is given by ωr, where ω is angular velocity and r is radius. So, v = 4 * 0.5 = 2 m/s.
