A robot fires a tennis ball to protect itself from an incoming baseball. The trajectory of the tennis ball shot from the robot is given by r(s)=⟨10−20s,103–√−203–√s,15s−5s2⟩, where r(0) is the position of the robot, and the baseball has a trajectory given by b(t)=⟨5t,53–√t,10t−5t2⟩, t≥0. At what time t0 should the robot fire the tennis ball so that it collides with the baseball?

they should be similar or the same

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
