This is a projectile motionm with
Iniital height, Yo = 2.4 m
Iniital vertical velocity, Voy = 0
Kind of motion: vertical fall => Y = Yo - Voy * t - [g*t^2] / 2
Initial horizontal position, Xo =0
Initial horizontal velocity, Vox = 22.3 m/s
kind of motion: uniform in the horizontal direction => X = Vox *t
You can find:
a) Height when the ball is passing the net, which is at 11.9 m from the service point.
Time when X = 11.9 m
X = Vox*t => t = X / Vox = 11.9 m / 22.3m/s = 0.5336 s
Replace that time into the vertical equation to find the height, Y:
Y = Yo - Voy*t - g*(t^2) / 2 = 2.4m - 0 - 9.8 m/s^2 * (0.5336 s)^2 / 2 = 1.0 m
Then, given that height of the net is 0.91 m, the ball will pass 0.09m over the net (9 cm).
b) How far from the net the ball will hit the ground, given that it is 11.9 m away of the service point.
From the vertical equation you can determine the flight time:
Y = Yo - g(t^2) / 2 => 0 = 2.4 - 4.9 t^2 => 4.9t^2 = 2.4 = > t^2 = 2.4 / 4.9 = 0.49 => t = √0.49 = 0.7 s
Now use that time in the vertical equation to find the X position of the ball when it hits the ground:
X = Vox *t = 22.3m/s * 0.7 s = 15.6 m
Then, subtract the position of the net to find how far away from it the ball hits the ground: 15.6 - 11.9 =3.7 m.
Astrology is the belief the positions of the stars and movements of the planets of the Solar System, and also asteroids and other stars, but not as much, have an influence on the events, lives, and behavior of people.
