Nancy is a pilot in Canada¡¯s North. She needs to deliver emergency supplies to a location that is 500 km away.

Question

Nancy has set the aircraft¡¯s velocity to 270 km/h on a northbound heading. The wind velocity is 45 km/h from the
east. Determine the resultant ground velocity of the aircraft.

Answer 1

same type as your previous question

resultant vector = 270(cos90, sin90) + 45(cos180,sin18)
= ....

then find the magnitude
