a book with a mass moves across floor when pushed with #N force at an angle. what is the coeff. of frictionK?

Question

mass is 325 N
force is 425 N
angle is 35.2 degrees

needing to find the coefficent of the kinetic friction aka "myoo-k"

Answer 1

Assuming constant velocity and that the angle is below horizontal

The forces all balance

425*cos(35.2)-(325+425*sin(35.2))*µk=0

µk=0.463
