A 5 kg box is sliding across the floor at 5 m/s. It hits another box that is 10 kg and is sitting still. After the impact, the 5 kg box is moving at 2.5 m/s. How fast is the second box moving?

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

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?
