Amuseum curator moves artifacts into place on various different display surfaces. if the curator moves a 145 kg aluminum sculpture across a horizontal steel platform with a force of 668n, what is the coefficient of kinetic friction?

Explanation:

As we know that the mass of the curator is

M = 145 kg

now the Force of kinetic friction on the curator is given as

now we know that the normal force on the curator is counter balanced by the weight of the curator

so we can say

Now from above formula we have
