Question

Calculate the coefficient of friction?

This was from a physics lab i recently did. I only have the angle theta, m, and L.

M=0.0954
Theta=17.2
L=1.22 m.

This is a block on an inclined track and the block is supposed to slide down with constant velocity at this angle.

Not really sure where to start after my vector diagram is complete.

Answer 1

Also m is in kg.

Answer 2

Draw a free body diagram. From it, find the component of the weight that is acting into the ramp, and the component acting down the ramp. There's a bit more to it than that, but this will get you to start thinking about the situation.

Answer 3

I got it, thanks!
