Finding net force and net acceleration

[jack612blue]

Homework Statement

A hamburger with a mass of 2500 kg was slided down a ramp that has a 45 degree incline, and the coefficient of kinetic friction between the hamburger and the ramp is .597. What is the net force acting on the hamburger? What is the net acceleration?

Homework Equations

Mass of burger= 2500 kg
mew k = .597

The Attempt at a Solution

The net force is mass times acceleration. But i don't have acceleration.

You have the acceleration due to gravity and the force due to friction. You have to find the component of the acceleration due to gravity which points down the ramp.

but I'm not sure if the object is at equilibrium?

The Attempt at a Solution

The net force is mass times acceleration. But i don't have acceleration.

Have you drawn a free body diagram? Use that to find the net force, not F=ma.
