  1. Question 1

    Q1. A body is moving in a circular path with a diameter of 4 m at a rate of 300 rpm. What is its linear speed?

    • A) 10π m/s
    • B) 20π m/s
    • C) 30π m/s
    • D) 40π m/s

    Answer: 20π m/s

    Explanation: First, find angular velocity (ω) = 2πf = 2π * (300/60) = 10π rad/s. Then, v = ωr = 10π * 2 = 20π m/s.
