O8232.474 mD. O15803.894 mE. 13428.572 m9. A bullet is fired from the ground making an angle of 20 degwith the horizontal with a speed of 1500 m/s.How far (horizontally) will it fall? (1 point)

Answer 1

The maximum height of a projectile is given by:

`h=(v_0^2\sin^2\theta)/(2g)`

In this case, the initial velocity is 1500 m/s, the angle is 20°; then we have:

`\begin{gathered} h=((1500^)^2(\sin20)^2)/((2)(9.8)) \\ h=13428.572 \end{gathered}`

Therefore, the maximum height is 13428.572 m
