Since the airplane is travelling at a constant height, then your j component stays the same.

Now, you know that the airplane is travelling at a constant velocity. You are given that in 30 seconds, it travels metres. So,

So how far will it have travelled in 70 seconds? This will be your i-component.

Now use that position vector and find its magnitude and angle with respect to the x-axis. - September 28th 2008, 12:47 PMyzc717Quote:
