A bowling ball is launched from the top of a building at an angle of 35° above the horizontal with an initial speed of 15 m/s. The ball lands on the ground 2.9 s after it is launched. What is the height of the building (in m)?

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?
