  1. Question 1

    Q1. A 2 kg block is attached to a spring with k = 100 N/m. If it is displaced by 0.2 m, what is its acceleration?

    • A) 5 m/s²
    • B) 10 m/s²
    • C) 15 m/s²
    • D) 20 m/s²

    Answer: 10 m/s²

    Explanation: F = -kx = ma, a = -kx / m = -100 * 0.2 / 2 = -10 m/s², using Hooke's law and F = ma.
