Function of friction is Force of Acceleration Fa = Force of Gravity Fg - Force of Friction Ff',

Fa = mass * acceleration

Fg = mass * acceleration of gravity nine.eight m/s^two

Ff = mass * acceleration of gravity * coefficient of friction Mu

First, you can see that mass cancels out so you are just left with a = a*g - Mu*ag

It's important to remember to calculate the forces on the correct angle. You need to calculate the normal force exerted on the you. Make sure you use the correct angles. Your formula should look like this:

This results in a = g*sintheta - Mu*a*costheta

zero.eight = nine.eight*sinforty - Mu*nine.eight*cosforty

Solve and get a Mu = zero.seventy-three

See the source link for a good example
