  1. Question 1

    Q1. A 20 N force is applied to a 10 kg body on a frictionless surface at 30° to the horizontal. What is its horizontal acceleration?

    • A) 1 m/s²
    • B) √3 m/s²
    • C) 2 m/s²
    • D) 1.732 m/s²

    Answer: 1.732 m/s²

    Explanation: Horizontal component of force = F cos(30°) = 20 * √3 / 2 = 17.32 N. a = F_horizontal / m = 17.32 / 10 = 1.732 m/s².
