Upon liftoff, a rocket flies through the air with a constant acceleration. After 15.0 seconds, its velocity is 7.4m/s. if you assume that the rocket started with zero velocity, what is its acceleration?

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?
