An Alaskan rescue plane drops a package of emergency rations to a stranded party of explorers. the plane is traveling horizontally at $30.0m/s$ at a height of $200.0m$ above the ground.

A)What horizontal distance does the package fall before landing?

B)Find the velocity of the package just before it hits the ground.

Two blocks with masses 4.00 kg and 8.00 kg are connected by string and slide down a 30.0 degree inclined plane. The coefficient of kinetic friction between the 4.00-kg block and the plane is 0.25; that between the 8.00-kg block and the plane is 0.35.

a) Calculate the acceleration of each block

b) Calculate the tension in the string

c) What happens if the positions of the block are reversed, so that the 4.00-kg block is above the 8.00-kg block?

A floating ice block is pushed through a displacement d=(15m)i-(12m)j along a straight embankment by rushing water, which exerts a force F=(210N)i-(150N)j on the block. How much work does theforce do on the block during the displacement?

Some have proposed that for a natural centrality measure, the most central a node can get is the center node in the star network. I've heard this called "star maximization." That is, for a measure $M(\cdot )$, and a star network ${g}^{\star}$ with center ${c}^{\star}$,

$\{({c}^{\star},{g}^{\star})\}\in {\mathrm{arg}max}_{(i,g)\in N\times \mathcal{G}(N)}M(i,g)$

where $N$ is the set of nodes and $\mathcal{G}$ considers all unweighted network structures.

I'd like to learn about some centrality measures that don't satisfy this property, but "star maximization" isn't a heavily used term, so I am having trouble in searching for many such measures. What are some such measures of centrality?
