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.
W = Fa Δd cosΘ
W = ½mv²
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.
