A plane takes off heading west at a ground velocity 500 kph and climbing at an angle of 8 degree. A 15 kph wind is blowing from the north. Determine the resultant air and ground velocities (:

Question

anonymous · Answer

take this problem one part at a time. first find the ground velocity of a plane going 500 kph at an angle of 8 degrees above horizontal.

anonymous · Answer

so I have to separate it ?

anonymous · Answer

cos I read it again and again, still don't understand the question :[

anonymous · Answer

why they gave us the ground velocity and then ask us ground velocity again?

anonymous · Answer

oh, I see. they do give you the ground velocity.

anonymous · Answer

|dw:1363583969040:dw| so you need to do a little trig to find the air velocity without wind.

anonymous · Answer

not bad. have you done the trig yet?

anonymous · Answer

yeah, but which part ?

anonymous · Answer

can you help me out, cos it is almost 1:30 AM here :[

anonymous · Answer

I'm gonna fall asleep :$

anonymous · Answer

ok
|dw:1363584645197:dw|
cos (8 degrees)= groundspeed/airspeed
