Ah true okay thank you sir, help very much appreciated, so then I would just do: gsinθ - ugcosθ = a Now does the equation above work? because I think I remember trying this cancelling out all of the m's, and I got a wrong answer, but I probably did my math wrong. I'll check once I finish with...

sorry I'm still confused, but which mass comes out? or all the masses cancel out? when i try that, I don't get the answer.

F=ma Fg - Ff = ma mgsin(theta) - umgcos(theta) = ma I have two masses to remove, not just one :/ So i can't just simply simplify to: gsin(theta) - ugcos(theta) = a right?

Homework Statement A crate is placed on an inclined board. The coefficient of friction between the crate and the board is 0.26 , and the angle of the slope is 16 degrees. Calculate the acceleration of the crate down the incline. Homework Equations F=ma Ff=umgcos(theta) Forge of gravity...

Homework Statement A sled takes off from the top of a hill inclined at 6 degrees to the horizontal. The sled's initial speed is 12 m/s. The coefficient of friction between the sled and the snow is 0.14. Determine how far the sled will slide before coming to rest. Homework Equations F=ma...

Homework Statement So basically this is a two part question, first part was find acceleration of the system (which i already found) with a coefficient of friction of 0.1. B) asks you what coefficient you need for the object not to move? Homework Equations The Attempt at a...
