Thrown at the same speed, a ball at 25∘ and a ball at 65∘ land at the same spot. Is that true for every pair of angles that add up to 90∘? You will make the program test it, and compare the times in the air.
The idea. On level ground,
R=gu2sin2θ
T=g2usinθ
Your tasks.
For each angle in the list, find its partner angle, 90∘ minus the angle.
Find the range of each angle, and the range of its partner.
Find the time in the air of each angle, and of its partner.
Do the tasks in the editor first, and run the checker after each one. Its hints help when a check fails. When you are ready, compare your code with this solution.
