A 2 kg metal plate slides down a 10m high slope. If the slope is 49 degrees, and the speed at the bottom is 8m/s what is the coefficient of friction?
This is what I tried:
Wf = F x d
I found the work done by Eg = Ek+Wf and then found d with 10/cos49... then I tried M = Ff/Fn (Fn found by mg) but then the answer I got was wrong... I don't know what to do next! Please help me!
Thanks
