Laws of Motion

Calculate the maximum acceleration of a moving car so that a body lying on the floor of the car remains stationary. The coefficient of static friction between the body and the floor is 0.15 (g=10 m s−2g = 10\ \mathrm{m\,s^{-2}}).

  1. A.1.2 m s⁻²
  2. B.150 m s⁻²
  3. C.1.5 m s⁻²✓
  4. D.50 m s⁻²

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
