<span>If a plane has a velocity of 300 km/h and a tailwind of 20 km/h, then the vectors of both forces would add (assuming that the tailwind is blowing exactly at the airplanes back) to a total of 320 km/h. Hope it helps

D) Kilograms is the standard unit of mass
Consider a car<span> that travels between points A and B.

I believe it is D. Earth spinning on it's axis.
