A student standing on a hill throws a snowball horizontally 4.5 m above the level ground toward a smokestack 15 m away. The snowball travels a path that includes positions A and B, shown in the diagram above. At which position, if either, is the magnitude of the snowball’s velocity vector greater? Justify your answer.

If the snowball hits the smokestack 1.2 m above the base, how fast was it thrown? (Think about what the y displacement of the snowball is)
