  1. Question 1

    Q1. A 5 kg block is pulled with a force of 20 N at 30° to the horizontal. What is its horizontal acceleration?

    • A) 3.46 m/s²
    • B) 2 m/s²
    • C) 4 m/s²
    • D) 1.73 m/s²

    Answer: 3.46 m/s²

    Explanation: Horizontal component of force = Fcos(30°) = 20 * √3 / 2 = 17.32 N. Then, a = F/m = 17.32 / 5 = 3.46 m/s².
