A plane flies at a speed of 150mph at an angle of 10 degrees, after 6 seconds, the plane keeps the same speed but changes to an angle 18 degrees. How long in minutes would it take the plane to travel to a cruising altitude of 30,000 feet?

Answer 1

change mph to feet/sec
(60mph=88fps)

speed=150*88/60=...

30,000ft=speed*6*sin10+speed((t-6)*sin18
solve for time t. then, divide by 60 to get minutes
