IF a plane flies at 200.0 km/h w/ respect to the air. what is the velocity of the plane relative to the ground if it flies with:
a. a 50-km/h tailwind?
b. a 50-km/h head wind?d
if you don't want to give me the answer? i understand but can you tell me how to do it and how to draw it?

You add the tailwind speed and deduct the headwind speed.

"w/ respect to the air" means that the plane is going exactly 200.0 km/h if you imagine the air standing still and the plane moving through it. Draw your pictures with arrows representing the speeds and directions of the plane and wind. Based on those diagrams, as the wind moves over the ground, what would a person standing on the ground measure if he looked up at the plane moving through the air?

Derwood H. S... is making things up. Even if drag was a factor, PI has nothing to do with it.
jessman8936 does not realize the headwind and the tailwind are two separate problems.
Heinz M is correct.

OK I have never taken a physics class but wouldn't the two equations cancel each other out? 50 tail wind (pushing) 50 head wind (pulling) comes out to Zero..... OK did I miss something?

Don't listen to Red Foreman....he is only partially right...you have to add the tailwind divided by pie (to account for drag) and then subtract the headwind divided by pie (to account for drag).
Yes it comes out the same but you always must account for DRAG!!!!!!

If you can't figure this one out by yourself, you shouldn't be in Physics class. You should be in basket weaving.
