Leanne is riding a bike. the forward force from her pedalling is 18n. there is a backward force of 6n from friction and a backward force of 12n from air resistance. does the speed of the bike increase, decrease or not change?

Which object is most likely represented by a dot?

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?
