Mixed Laws of MotionHardQuestion 5457

Question

A 10 kg block on rough surface (μₛ = 0.5, μₖ = 0.4) is pushed by 40 N. Acceleration (g = 10 m/s²):
  1. A
    0 m/s²
    Correct
  2. B
    2 m/s²
  3. C
    1 m/s²
  4. D
    4 m/s²

Correct answer

0 m/s²

Explanation

Max static friction = μₛmg = 50 N > 40 N (applied force). Block does not move. Acceleration = 0 m/s².
