So an airplane is traveling northeasterly at 250 kilograms per hour.
00:08
So when it says northeasterly, we can assume a perfect 45 degree angle.
00:14
And so we'll get that 250.
00:19
And then there is a wind that is going towards the east at 50 kilometers per hour.
00:30
And then it asks, so really, the 250 is the resultant and that's why i didn't do him tip to tell because i wouldn't consider with our 50 kilometer per hour wind and with what the plane would have normally been traveling it results in that 250 so what we're really trying to find is kind of one of the vectors that would be you know added together to result in that 250 so that's how we're going to write it the velocity of the plane, we don't know.
01:02
We'll say v of x in the i direction and v of y in the j direction.
01:07
We're going to solve for that.
01:08
Now, our wind is just 50 in the i direction and zero in the j direction.
01:14
And then when these are added together, it should result in that 250...
