1. The problem statement, all variables and given/known data Consider the following two scenarios with the same box sliding up two differently inclined ramps. The coefficient of static friction is 0.7, the coefficient of kinetic friction 0.5. Eventually, the box will stop. Up to what maximum angle of the incline (in degrees) would it not slide back down? 2. Relevant equations sin = o/h cos= a/h tan= o/a 3. The attempt at a solution cos-1 (.7/.5) = error cos-1 (.5/.7)= 44.41 = wrong cos-1 (.4) = 66.42= wrong cos-1 (1) = 0 so I thought it could also equal 360 so I added 360+66.42 = 426.42 = wrong sin-1 (.7/.5)= error sin-1 (.5/.7) =45.58 (I think its wrong) tan-1 (.7/.5) = 54.46 = wrong tan-1 (.5/.7)= 35.53 = scared to try to see if its wrong HELP PLEASE !!!!!!!
