Ax=vot + zat 2 When the height of the object increases, the time of the object will also increase. When the time increases, the distance (x) will increase according to the kinematic equation above. 4. How would quadrupling the height affect the horizontal range, if fired horizontally? Quadrupling the height will double the horizontal distance. 5. Using the simulation, how does changing the vertical velocity affect the horizontal range? By increasing the vertical velocity, the horizontal range will also increase. Vise versa.
