A block is at rest on an inclined plane whose elevation can be varied. The coefficient of static friction is μs= 0.350, and the coefficient of kinetic friction is μk= 0.160. The angle of elevation θ is increased slowly from the horizontal. At what value of θ does the block begin to slide (in degrees)?

Best ResponseYou've already chosen the best response.0\[mgsin \theta  mg \cos \theta \mu k =0\] \[mgsin \theta = mgcos \theta \mu k \] \[\sin \theta = \cos \theta \mu k\] \[\tan \theta = \mu k\] \[\theta = \tan^{1} \mu k\]
