A plane, diving with constant speed at an angle of 53.0degrees with the vertical, releases a projectile at an altitude of730 m. The projectile hits the ground 5.00 s after release.
A) what is the speed of the plane?
B) how far does the projectile travel horizontally during itsflight?
C) What are the horizontal component of its velocity justbefore striking the ground?
