Consider the motion of a bullet fired straight down from the top of a high cliff.
Consider only the motion after the bullet has
left the barrel of the gun and before it hits the
ground. Ignore air resistance.
What is the magnitude of the acceleration
of the bullet during this motion?
1.Equal to 9.8m/s^2
2. First less than 9.8 m/s², then greater
3. More than 9.8 m/s2
4. Equal to 0
5. First greater than 9.8 m/s2, then less
6. Less than 9.8 m/s2
Who is the answer !?

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?
