A 100kg box is pushed along a road with force of 500N. If the box moves with a uniform velocity, the coefficient of friction between the box and the road is

  • 0.4
  • 1.0
  • 0.8
  • 0.5 checkmark

The correct answer is: D

Explanation

Coefficient of friction μ = F/R = F/mg = 500/1000 = 0.5
∴ μ = 0.5
