What is the acceleration of a car with a final velocity of 25 m/s if the initial velocity was 1 m/s and it takes 6 seconds? a = (Vf - Vi)
Δt
a 150 m/s2
b 4 m/s2
c – 4 m/s2
d 32 m/s2

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?

What is the momentum of a 2 kg object moving at 15 meters per second

Newton's second law states that f = m x a (force is mass times acceleration). which example would have the greatest acceleration?
