Hi - I'm needing help with this one - cannot quite get it. Thanks
An airplane in level flight at an altitude of 7000 m is moving at 500 m/s. At the moment it flies overhead, a ground missile is fired at a constant acceleration of 80 m/s/s. What aiming angle above the ground must be used to hit the airplane?
It seems from your responses that you are not confident in using your algebra and trig skills.
If such is the case, then I recommend you solve the equation using your calculator. If your calculator skills are wanting, then I advise that you have a face-to-face session with your instructor.
