Question

an object of mass 150kg is pulled on a horizontal rough ground by a force of 900newton(N).find the coefficient of static friction (taken g=10m/s)

Answer 1

Cannot work, not enough information. Is the object at constant velocity?

Answer 2

I think the answer is: Fs=mg=150kg x 10m/s^2=1500N then Coefficient of sf=Fs/Fn = 1500N/900N =1.66
