Problem reads: A package case of mass m is left 10 m up on a 30 degree ramp overnight where it is at rest. a) what is the minimum value of the static coefficient of friction for this to be ture? Prove in general that the coefficient of static friction is [tex]\mu_s = \tan \theta [/tex]. b) during the night itrains and water seeps under the case reducing the coefficient of friction to .10 (both static and kinetic). With what speed does the case reach the bottom of the ramp?
Ok... can I move on with part a without mass of the object? I am trying to move forward with [tex] F_{s} max = \mu_s FN [/tex]
Oh man, physics...
