(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A large package weighing 517 N is accelerated across a gym floor at 3 m/sec^2 because it is being pushed at a force of 285 N at 50 degrees to the floor. What is the normal force of the package? What is the coefficient of sliding friction between the package and the floor? Approximately what percentage of the 285 N force is being wasted due to the excessive angle produced by the pusher?

2. Relevant equations

F=MA

HORIZONTALLY

FORCE APPLIED, X= (285)(cos 50)= 183.194

VERTICALLY

FORCE OF Y=0 (not rising off the ground)

FORCE APPLIED, Y= (285)(sin 50)= 218.323

3. The attempt at a solution

I have filled in as much as I know, please help!

Thanks
