Rather than rotate completely horizontally, a carousel rotates at an angle of 10° from horizontal, with a constant angular velocity of 1.571 RAD/s. A box is placed 1.5 m from the axis of rotation. What’s the minimum coefficient of static friction so the box will not slip?

The maximum force on the box will be on the lower side, centripetal force+gravity.

mw^2 r + mgSin10=mu*mg*cos10
