A plane traveling horizontally at 0 m/s means the plane is essentially stationary in the horizontal direction (not moving forward or backward). In this scenario, if the plane drops any object, the object will simply fall vertically downwards due to gravity, since there is no initial horizontal velocity component carried by the object. In projectile motion terms:
- Horizontal velocity vx=0 m/sv_x=0,\text{m/s}vx=0m/s
- The object experiences no horizontal acceleration ( ax=0a_x=0ax=0 )
- The object will have vertical velocity increased by gravity acceleration ay=9.8 m/s2a_y=9.8,\text{m/s}^2ay=9.8m/s2 downward.
- The motion is purely vertical free fall starting with zero vertical velocity.
Thus, the object dropped from the plane will fall straight down along a vertical path.
