Earth curve equation

The radio horizon is the locus of points at which direct rays from an antenna are tangential to the surface of the Earth. If the Earth were a perfect sphere without an atmosphere, the radio horizon would be a circle. The radio horizon of the transmitting and receiving antennas can be added together to increase the effective communication range.

WebAug 11, 2024 · The final vertical velocity is given by Equation 4.4.4: vy = v0y − gt. Since v0y was found in part (a) to be 21.2 m/s, we have vy = 21.2m / s − (9.8 m / s2)(3.79s) = − 15.9 m / s. The magnitude of the final velocity →v is v = √v2 x + v2 y = √(21.2 m / s)2 + ( − 15.9m / s)2 = 26.5 m / s. Intuitively, the curvature describes for any part of a curve how much the curve direction changes over a small distance travelled (e.g. angle in rad/m), so it is a measure of the instantaneous rate of change of direction of a point that moves on the curve: the larger the curvature, the larger this rate of change. In other words, the curvature measures how fast the unit tangent vector to the curve rotates (f…
