A student fires a cannonball diagonally with a speed of 22.0m/s from a height of 42.0m as shown. Neglect drag. Determine all unknowns and answer the following questions.
How long did the ball rise?
What was the ball's maximum height above the ground?
How long did the ball remain in the air?
How far from the base of the building did the ball land?
How fast was the ball moving as it struck the ground?
At what angle (with the horizontal) did the ball land?
Calculate the magnitude of the angle between the final velocity vector and the nearest horizontal. Answers should be between 0 and 90°.
Please refer to the picture attached.

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
