An object that starts at a position of 5 m and travels for 3 s at a velocity of −9 m/s ends up at what position?

So Velocity = final position - initial position divided by time. We are looking for The final position so let's plug in what we know and go from there.

V = -9 m/s Xf = ? Xi = 5m T = 3s

to solve

-9 m/s = (X - 5m) / 3s

-9 x 3 = X - 5

-27 + 5 = X

Xf = 32 m (distance can't be in negative, so we disregard that)

(Hopefully this is right, I haven't done any physics since last year. But it shouldn't be too far off)

the higher the current the higher the mag field around it the higher the influence on the compass
