Arock is thrown upward from the level ground in such a way that the maximum height of its flight is equal to its horizontal range r. in terms of the original range rmax, what is the range rmax the rock can attain if it is launched at the same speed but at the optimal angle for maximum range?

Explanation:

If the maximum height attained by the rock is equal to the range of the rock

then we will say

so from this we can say

now original range is given as

now we know that for maximum possible range we need to throw at 45 degree

a electromagnetic waves

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
