A6,0 kg box is at rest on a table. the static friction coefficient u, between the box and table is 0.40, and
the kinetic friction coefficient pen is 0.20. then, a 30 n horizontal force is applied to the box,

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
