The ball is thrown horizontally from a height of 2 m so that it flies to the surface of the earth at an angle of 45 degrees to the horizon. What is the horizontal distance the ball flew?

Given:
h = 2m
a = 45 °
y = 0
S-?
Decision :
First you need to paint the tangent of this angle:
tga = Vy / Vx from this it follows that
Vo = gt
S = Vot
S = gt ^ 2 = 2H
S = 2 * 2 = 4m
Answer: 4m
