Homework Statement


a moving object whose initial kinetic energy is 20 Joules is subject to a frictional force of 4 N that acts in the opposite directon. how far will the object move before coming to a stop.


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
Oh super...

What is the definition of work?
 
work p=w/t
 
you sure?

P is power, I believe. (I'm not that far in physics yet, but I am in the work section.) :)

Should be something involving these variables: W, F, and s.
