This is the equation of a parabola, so the path is parabolic. The axis of the parabola is vertical. If the projectile's position (x,y) and launch angle (θ or α) are known, the initial velocity can be found solving for v 0 in the afore-mentioned parabolic equation:
The paraboloid of revolution obtained by rotating the safety parabola around the vertical axis is the boundary of the safety zone, consisting of all points that cannot be hit by a projectile shot from the given point with the given speed.
The green path in this image is an example of a parabolic trajectory. A parabolic trajectory is depicted in the bottom-left quadrant of this diagram, where the gravitational potential well of the central mass shows potential energy, and the kinetic energy of the parabolic trajectory is shown in red. The height of the kinetic energy decreases ...
For a parametric equation of a parabola in general position see § As the affine image of the unit parabola. The implicit equation of a parabola is defined by an irreducible polynomial of degree two: + + + + + =, such that =, or, equivalently, such that + + is the square of a linear polynomial.
The scale factors for the parabolic coordinates (,) are equal = = + Hence, the infinitesimal element of area is = (+) and the Laplacian equals = + (+) Other differential operators such as and can be expressed in the coordinates (,) by substituting the scale factors into the general formulae found in orthogonal coordinates.
A popular salty snack is being recalled. Frito-Lay issued a limited recall on Monday Dec. 16 for 6,344 of its 13-ounce bags of Lay’s Classic Potato Chips, an alert from the Food and Drug ...
Then there were 12. On Sunday, the College Football Playoff selection committee unveiled the first-ever 12-team CFP bracket putting an end to much build-up and anticipation on which 12 college ...
Ages: 12 months+. These colorful plastic blocks are a classic gift for two year olds for good reason: the large size pieces are easy for them to manipulate, and don’t pose a choking hazard like ...
