The maximum horizontal distance travelled by the projectile, neglecting air resistance, can be calculated as follows: [1] = ( + +) where d is the total horizontal distance travelled by the projectile.
The range and the maximum height of the projectile do not depend upon its mass. Hence range and maximum height are equal for all bodies that are thrown with the same velocity and direction. The horizontal range d of the projectile is the horizontal distance it has traveled when it returns to its initial height (=).
Rifleman's rule is a "rule of thumb" that allows a rifleman to accurately fire a rifle that has been calibrated for horizontal targets at uphill or downhill targets. The rule says that only the horizontal range should be considered when adjusting a sight or performing hold-over in order to account for bullet drop.
A person using the stairs would move this distance forward with each step they take. To avoid confusion, the number of steps in a set of stairs is always the number of risers, not the number of treads. The total run or total going of the stairs is the horizontal distance from the first riser to the last riser. It is often not simply the sum of ...
Experiment to determine the trajectory of an outflowing jet: Vertical rods are adjusted so they are nearly touching the jet. After the experiment the distance between a horizontal line and the location of the jet can be measured by the length adjustments of the rods. Every physical theory must be verified by experiments.
Spicy Chick-Fil-A Chick-n-Strips. For those who crave a kick of heat, Chick-fil-A’s Spicy Chick-n-Strips were a standout hit. Chicken breast strips seasoned with a spicy blend of peppers quickly ...
Diagram of measurements: D is the slant distance; S is the horizontal distance; Δh is the vertical distance. Tacheometry ( / ˌ t æ k i ˈ ɒ m ɪ t r i / ; from Greek for "quick measure") is a system of rapid surveying , by which the horizontal and vertical positions of points on the Earth's surface relative to one another are determined ...
The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation , it is a special case of a more general formula in spherical trigonometry , the law of haversines , that relates the sides and angles of spherical triangles.
