A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.09 s later. You may ignore air resistance.

A-If the height of the building is 20.0 m , what must the initial speed be of the first ball if both are to hit the ground at the same time?

B-Consider the same situation, but now let the initial speed V0 of the first ball be given and treat the height h of the building as an unknown. What must the height of the building be for both balls to reach the ground at the same time for V0= 8.75 m/s.

C-If V0 is greater than some value Vmax , a value of h does not exist that allows both balls to hit the ground at the same time. Solve for Vmax .

D-If V0 is less than some value Vmin , a value of h does not exist that allows both balls to hit the ground at the same time. Solve for Vmin .

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?
