Compute each part of given question:
Question: An airplane, diving at an angle of 57° with the vertical, releases a projectile at an altitude of 750 m. The projectile hits the ground 4.48 s after being released.
Part A: What is the speed of the aircraft?
Part B: How far did the projectile travel horizontally during its flight?
Part C: What was the horizontal component of its velocity just before striking the ground?
Please give me an explanation for above question.
