In preparing for a test I came across this problem:
A box is given a push so that it slides across the floor. How far will it go, given that the coefficient of kinetic friction is 0.2 and the push imparts an initial speed of 3.0m/s?
Here's what I've come up with so far:
Fapplied - Ffriction = ma
V0=3, x=?, a=?, Vf=0
Vf^2=Vo^2+2ax;
0=3^2+2ax
-9=2ax
I can't come up with any more equations, and there are currently too many variables to put the equations together. It seems pretty straightforward--perhaps I'm just missing something crucial.
