`x = cos(theta)*V*t`

Enter a value for all fields

The **Horizontal Position **calculator computes the horizontal (x component) position based on an initial velocity, launch angle, and time.

**INSTRUCTIONS**: Choose units and enter the following:

**(V**Magnitude of Initial Velocity_{0})**(Θ)**Launch Angle**(h)**Initial Height above the Plane**(t)**Time into the ballistic flight.

**Position (x,y):** The calculator returns the relative X and Y position in meters. However this can be automatically converted to compatible units via the pull-down menu. The calculator also returns:

- Max Altitude
- Max Range
- Time of Flight

The **Ballistic Horizontal Position** equation calculates an object's position in the x direction, the horizontal component of its ballistic trajectory. This is the equation for the ideal projectile, which means it neglects external forces such as air resistance. Since in the ideal projectile motion model the force of gravity is the only force component affecting the trajectory, and the force of gravity is parallel to the y-component of motion, the gravitational acceleration has no affect the ballistic x-velocity. The x-component of position changes based on the time and the horizontal velocity. The formula for the horizontal position is:

where:

- x is the horizontal position
- V
_{0}is the initial velocity - θ is the launch angle
- t is the time into the flight

- Ballistic Maximum Altitude: This is the maximum altitude achieved in free ballistic flight.
- Ballistic Maximum Range: This is the maximum horizontal range.
- Ballistic Flight Time: This is the time duration of free flight.
- Ballistic Vertical Velocity: This is the vertical velocity at a given time.
- Ballistic Horizontal Velocity: This is horizontal velocity or ground speed.
- Vertical Position in Ballistic Flight: This compute the vertical position (y) at a given time within ballistic flight.
- Horizontal Position in Ballistic Flight: This compute the horizontal position (x) at a given time within ballistic flight.
