## Homework Statement

G: m=50 kg, W= 2.2E3 J, (delta)d=60 m, speed is constant, coefficient kinetic friction = 0.26

R: Force applied, and angle

## Homework Equations

These are the equations I have:

W = F(delta)d cos(theta)

## The Attempt at a Solution

The velocity is constant, so net force must be 0. Therefore, I thought that applied force must be equal to force of friction, or (mu)Fn. This doesn't account for the angle, and is incorrect.

Can anyone offer help? I get the feeling I'm only missing some basic equation. Thanks!
