Quiz 56: The bullet
A gun shots a bullet with an inclination of 30° and a speed of 300Km/h. Which is the distance "d" before the bullet touches the ground again?

Guys, very easy:
1) A=Vcos(30) horizontal speed (constant)
2) B=Vsin(30) starting vertical speed
3) x(t)=At
4) y(t)=Bt-1/2gt^2

From 4, T=2B/g, where T is the time the bullet reaches the ground.

Putting T in 3, we get:
X=2AB/g
