Answer:

47.5 N

Step-by-step explanation:

Given

  • mass, m = 100 kg
  • coefficient of static friction, μ(s) = 0.5
  • coefficient of kinetic friction, μ(k) = 0.3
  • gravity due to acceleration, g = 9.5 m/s²

Solving

  • It asks the required force to get it moving ⇒ static friction
  • Force required to move = μ(s) x m x g
  • F = 0.5 x 100 x 9.5
  • F = 95 x 0.5 = 47.5 N
