An airplane is being floen at 1500km/h at 100m above level ground. The ground began to rise up at 10 degrees. How much time does the pilot have to madke correction such that the plane doesn't hit the ground?

the part where the ground is rised to 10 degrees confuses me.

You know the height is 100m. If the angle is 10 degrees, calculate tan angle = 100m/x where x will be the forward distance to reach the 100m height. Then use distance = rate x time to calculate time required. It will be VERY short. Don't forget to change km to m and remember the answer will be in hours.

10 seconds
