## Homework Statement

A man pulls a wooden crate across a floor by a rope.

Mass of the crate = 15Kg

Force the man pulls with = 65N

Acceleration of the box = 20 M/s²

What is the angle to the horizontal at which the man pulls the rope.

## Homework Equations

W = Fa Δd cosΘ

W = ½mv²

(think)

## The Attempt at a Solution

I clearly don't understand this, but at first I figured I would use W = Fa Δd cosΘ and just rearrange the equation, then I realized, I don't have Work, figured I would find that using

W = ½mv². Then I realized I don't have Velocity, I can't find velocity without distance and I can't find distance without time.

I'm lost.
