I have this problem to do for homework for my physics class and I don't even know where to start! Could someone try to give me clues? The problem is: A pilot flies horizontally at 1300 km/h, at height h= 35 m above initially level ground. However, at time t = 0, the pilot begins to fly over ground sloping upward at angle theta = 4.3 degrees. If the pilot does not change the airplane's heading, at what time t does the plane strike the ground? thank you so much!
