Homework Statement
A crate of bananas has an initial speed of 4.2 m/s2. It slides across a floor, traveling 6.0m before coming to a stop. Find the coefficient of kinetic friction between the crate and the floor.
Homework Equations
Fnet=ma
v2=v02+2aΔx
The Attempt at a Solution
v=4.2 m/s
x=6.0 m
vf=0
Δx=6.0 m
a=v2-v02/2x
a=0-17.64 m/s2/12 m = 1.47m/s2
[itex]M[/itex]N=ma
mg=a
mg=a/g
m=1.47 m/s2/9.8m/s2=.15
For a final answer of .15. This seems correct to me, but could someone please confirm?
Sorry about the doubled template, I don't know how to get rid of it without messing up my post! Any ideas?
