I think you solve it like this...do you have the answer to verify? I am no genius in physics...
Forces in the x direction = friction = mass x acceleration.
friction forces is found by multiplying the coefficient of friction (u) by the normal force.
so. -u x mass x gravity = mass x -acceleration
mass cancels so u = 1.39 / 9.8.
atta go Brenda !
