You need to use the absolute value $-|\mu \cos \alpha|$ in the calculator because you know that friction will always oppose the motion (making it negative). Really you have to constrict your problem between 0° and 90° because outside of that range you aren't really representing the situation anymore. That equation only holds while the block is on the slope, which only happens between 0° and 90°. | |
