Question

An airplane is flying due west at a velocity of 100 m/s. The wind is blowing out of the south at 5 m/s. What is the magnitude of airplane's resultant velocity?

Answer 1

now use pythagorean theorem
100^2 + 5^2 = Resultant ^2
sqrt ( 100^2 + 5^2 ) = resultant

Answer 2

resultant = 100.1249
