Calculate the coefficient of sliding friction if the friction force is 2.5 N, and the body weight is 3.5 N?
| February 11, 2021 | education
Ftr = 2.5 N.
P = 3.5 N.
k -?
Ftr = k * N, where k is the coefficient of sliding friction, N is the force with which the body acts on the plane along which it slides.
According to Newton’s 3 law, the force N = P, the formula will take the form:
Ftr = k * P.
k = Ftr / P.
k = 2.5 N / 3.5 N = 0.71
Answer: the coefficient of sliding friction is k = 0.71.
