A ladder of length L = 2.8 m and mass m = 19 kg rests on a floor with coefficient of static friction μs = 0.48. Assume the wall is frictionless. 1)What is the normal force the floor exerts on the ladder? 2)What is the minimum angle the ladder must make with the floor to not slip?

It's lengthy to explain, so I'm keep thinking to go shortcut :( However the angle is = arctan ( 1/.98) = 45.58 degree.
