You're right the only force would be friction force.
So,
Ff = uk * Fn
Ff = .86 * 88.2 N
Ff = 75.9 N
With friction force i can find energy.
E = F * d
E = 75.9 N * 12.25 m
E = 929.8 J
So now that i know the energy my next step is to find velocity.
KE = (1/2)mv^2
KE = E
929.8 J =...
Hmmm I haven't thought about finding energy.
Since Energy = net force * distance I will need to find net force and I already have distance.
And Fnet = Ff + Fa
Ff = (uk)(Fn)
Ff = 75.8 N
But how do I find Fa?
