We used vector to find wind speed.

A balloon is timed as it rises inside, assume a *vertical component only

The balloon is taken outside, and timed. The angle it makes is also recorded.

Using the vectors, calculate the wind speed.

i used the law of cosines to determine the magnitude of the resultant.  Was that correct to do?

amistre64 · Answer

Teacher wanted us to use pythag thrm to determine the wind speed.  But the data collected gave a sqrt(-#) which would not allow the pythag thrm to be used.

I decided to take the more general Law of Cosines.

amistre64 · Answer

i did try it, and since the hypotenuse is smaller than the "leg", it results in a non-real value.

amistre64 · Answer

his assumption is that the wind never blows things downward i spose

amistre64 · Answer

speed = distance/time

speed up = 1.05 m/s
speed along the angle = .97 m/s
