A glass slides across a bar and slows down due to a kinetic friction of 0. 175N. If the glass weighs 0. 500N, what is the coefficient of kinetic friction between the glass and the bar?

Respuesta :

Answer:

F = M a = Ff     force of friction

Ff = μ M g = μ W         where M g = weight of glass

The problem gives the kinetic friction as a force (Ff) in Newtons

μ = Ff / W = .175 / .500 = .35
