How do i solve this

Posted on 2014-03-13 08:39:00 in Math by BAILS

I have a maths assignment due and I dont know how to solve question two. I will put question 1 and 2 up, as they lead after each other. Please explain how you got the answer too. Thanks.



1)

Draw a diagram of a flight controller (45m off the ground) sighting a plane at a constant altitude at an angle of elevation of 14 degrees from her eyesight. 7 seconds later the aeroplane flies directly overhead. (This I could do)



2) (This I cant)

If the aeroplane has a constant speed of 370km/h, what distance, in metres, did it cover between the time the flight controller first observed the aeroplane to when it passed overhead?

This is so hard!!!!!!



(I will put 3 4 and 5 up incase you guys are so kind to answer them for me too :3)



3)

Calculate the aeroplanes height above the ground, in metres (I can do this one)



4) On reaching the tower, the aeroplane climbed for the next 12 seconds without changing speed to reach a new altitude of 1000m. What would its angle of ascent be during this time?



5)

How far has the aeroplane travelled horizontally since it was first sighted?



Thanks :D
