Solve the all parts of given problem:
Problem: Suppose a projectile is to be launched at 35 degrees to the horizontal, from point A, at a vertical distance of 3.3 km and a horizontal distance of 9.4 km?
Part A: Calculate the initial speed required to satisfy the above conditions?
Part B: Calculate the time of the flight of the projectile using the initial from part (a)?
Don't just give me the answer; explain your steps as well.
