TWO BALLS EXCHANGED

Pleaseee help:)

Two balls are on the earth's surface and are separated by l (see the picture). The second object is thrown with the same initial velocity v, the elevation angle of each of $\alpha$ and $\beta$. After experiencing a parabolic motion, the position of the two objects exchanged. If air friction ignored:

a. Determine the relative position of the ball A to B for each time t

b. Draw the path of ball A when viewed by the ball B

c. Determine the relative speed of ball A to B for each time t

d. Determine the angle between the relative velocity ball A to B with the relative position between the ball A against B for each time t

e. Determine the minimum distance between two objects when at least one of the objects is still in the air

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
