place these steps in finding the distance a horizontally launched projectile will travel before it hits the ground in order from first to last.
① instructions
use the equation $y_f = y_i + \frac{1}{2}a_y t^2$ to describe the projectile’s vertical motion.
solve for the time of fall.
solve for the horizontal distance.
use the equation $x_f = v_x t$ to describe the projectile’s horizontal motion.

Explanation:

To find the horizontal distance of a horizontally launched projectile, first analyze vertical motion (since time of fall depends on vertical displacement), solve for fall time, then use horizontal motion equation with that time to find distance.

Answer:

1. Use the equation $y_f = y_i + \frac{1}{2}a_y t^2$ to describe the projectile's vertical motion.
2. Solve for the time of fall.
3. Use the equation $x_f = v_x t$ to describe the projectile's horizontal motion.
4. Solve for the horizontal distance.
