a certain airplane has a speed of 180 mi/h and is diving at an angle of 30.0 degrees below the horizontal when a radar decoy is released. The horizontal distance between the release point and the point where the decoy strikes the ground is 2300 ft. (a) How high was the plane when the decoy was released? (b) how long was the decoy in the air?
The Attempt at a Solution
I tried converting every distance unit to meters and got the velocity was 80.45 m/s
and the horizontal vel = 69.67 m/s
vertical vel = 40.225 m/s
but then I had to find part b before I could answer part a?
p.s. the answers I got were a) 1657.67m and b) 22.95 sec.
i dont think this is right
