SUMMARY

The discussion focuses on calculating the acceleration of a ship launched down a ramp inclined at 8 degrees, with a coefficient of kinetic friction (Mk) of 0.06. The relevant equations include the force of gravity acting along the ramp (f = mg sin(θ)) and the normal force (N = mg cos(θ)). The net force equation (Fx = max = Fgx + f) is utilized to derive the acceleration formula, leading to the conclusion that acceleration can be determined by the equation max = mg sin(θ) - Mk * mg cos(θ).

A ship is launched into the water down a ramp making an angle of 8 degrees with the horizontal. The Coefficient of kinetic friction between the boat and the ramp is Mk = 0.06. What is the acceleration?

What have you tried?
 
I'm not sure which formula to use.
There's f=mg sin0=MsN
N=mg cos0
Fx=max=Fgx +f
max= mg sin0 - Mmg cos0
Mk=Fkx/N
