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
