Ff= force of friction
U= coefficient of friction
Fn= force normal
m=mass
g=acceleration due to gravity =9.81
a= acceleration
d=distance
Ff=UxFn
which is the same as
m x a= U x m x g
divide out the m and you get
a=U x g
and so
a=.04 x 9.81
a= .3924
so is it slowing down by .3924 m/s^2?
how do I link the velocity, time, and acceleration now?
