El cubo A tiene masa de 4.00 , y el cubo B, de 12.0 . El coeficiente de fricción cinética entre el cubo B y la superficie horizontal es de 0.25. ¿Qué masa tiene el bloque C si el cubo B se mueve a la derecha con aceleración de 2

If the force on an object is in the negative direction, the work it does on the object must be [2 points a) negative. b) positive c) the work could be either positive or negative, depending on the direction the object moves

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?
