physics help!!! Ok, I have understood every problem we have done so far except this one, You are wearing shoes that have a coefficient of friction on rock of 0.70. On how steep a rock slope could you stand without slipping? So far i have gotten: Fs=Fparallel= mu*W*costheta = W*sinTheta w=mg but if u cancel weights I got: mu*costheta = sintheta Im probably completely wrong, but thats what i got. Thanks in advance.
