A pilot flies horizontally at 1300 km/hr at height 35m above initially level ground. At t= 0 the pilot begins to fly over ground sloping upward at an angle of 4.3 degrees. If the pilot does not change his heading, at what time will he hit the ground?

2. Relevant equations

Kinematics equations, and maybe trig.

3. The attempt at a solution

I have two ideas on how to start this problem. First was to think of the plane as going down at the angle of 4.3 degrees and the ground being flat and draw a triangle. But I felt like I was on the wrong track.

Then I was thinking to think of the airplane as sitting still, and the ground coming up toward it a 4.3 degrees and 1300 km/hr.

Are either of these the right way to solve this problem?

Thanks
