## Homework Statement

A 98 N box of oranges is being pushed across a horizontal clean steel surface until it stops. As it moves, it is slowing down at a constant rate of 1.1m/s each second. The push force has a horizontal component of 25N and a vertical component of 20N downward. Calculate the coefficient of kinetic friction between the box and the floor.

## Homework Equations

## The Attempt at a Solution

summation of Fx = 25N - fk = ma

= 25N - fk = (10kg)(1.1m/s^2)

fk = 14N???

summation of Fy= 0 = -Fw - Fdown +normal force

normal force = 20N + 98N = 118N???

fk = (uk)(Fn)

(14N / 118N) = uk

uk = 0.119
