Mark loves sliding always. He slides at the park with 41° in the down direction. Jim slides on another sliding path with the same Mark sliding angle. Jim spends half the time that Mark needs to slide. Find the friction coefficient?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.
