Answer» Given: Force of 294N is required to START moving an OBJECT of 100kg in a horizontal plane. To Find: coefficient of friction. Solution: Coefficient of friction, μ = F / N Where F is the frictional force and N is the normal reaction N = mg ⇒ N = 100 x 9.8 = 980 N Now, it is given that F = 294 N Putting these VALUES in the formula, μ = (294 / 980) = 0.3 Hence, the coefficient of friction is 0.3 |
