what formula do i need to solve this problem?
A sled of mass 57 kg is pulled along snow-covered, flat ground. The static friction coefficient is 0.30, and the sliding friction coefficient is 0.10.
What does the sled weigh?
Force = mass * acceleration
Weight = mass * g

how do i find the coefficient of frcition?
You don't need to find it. It's given. It's also irrelevant to the problem. The problem just asked you for weight -- all you need is mass and the acceleration due to gravity (9.8 m/s^2).

oh, im sorry. maybe i should've been more specific. If I was just givin the force, the mass and acceleration. I'm not given the coefficient of friciton or the frictional force.
I have no idea what you're asking. Are you talking about some new problem now?
