Question

An object is known to have a coefficient of kinetic friction (µk) of 0.167 and a coefficient of static friction (µk) of 0.42. If the normal force is 200 N, how much frictional force will it encounter while it is moving?

    Answer:

    Ff = 33.4N

    Explanation:

    To find the frictional force while the object is moving, you take into account that the friction force depends of the coefficient of kinetic friction.

    The frictional force is given by:

    F_f=\mu_kN         (1)

    Ff: frictional force = ?

    µk: coefficient of kinetic friction = 0.167

    N: normal force of the object = 200N

    You replace the values of the parameters in the equation (1):

    F_f=(0.167)(200N)=33.4N

    The frictional force, while the objects is moving, is 33.4N
