Question

What do you need to know to be able to determine how far a projectile travels horizontally?

Check all that apply.

A. The height of the projectile path
B. The length of time before it lands
C. The acceleration of gravity
D. The horizontal velocity of the projectile

Answer 1

As for me, there are two suitable answers for the question represented above and here is a short explanation why I consider these two to be correct :
D. The horizontal velocity of the projectile and B. The length of time before it lands

`v_x = v*cos(x) [ d_x = v_x(t) + ½at²` -- this led me to answers! Hope everything is clear! Regards!
