Question

An object on a level surface experiences a horizontal force of 12.7 N due to kinetic friction. The coefficient of kinetic friction is 0.39.

1) What is the mass of the object in kg?

Answer 1

Answer #1

Let the mass be m.
Now,
the coefficient of kinetic friction,n = 0.39
So,
Force,F = n*mg
=> 12.7 = 0.39*9.8*m
=> m = 3.323 kg
