  1. Question 1

    Q1. A wheel starts from rest and attains an angular velocity of 5 rad/s in 2 s. What is its angular acceleration?

    • A) 1 rad/s²
    • B) 2 rad/s²
    • C) 2.5 rad/s²
    • D) 3 rad/s²

    Answer: 2.5 rad/s²

    Explanation: Angular acceleration (α) = Δω / Δt = 5 / 2 = 2.5 rad/s², using the formula α = Δω / Δt.
