WebThe position vectors are drawn from the center of Earth, which we take to be the origin of the coordinate system, with the y-axis as north and the x-axis as east. The vector between them is the displacement of the satellite. We take the radius of Earth as 6370 km, so the length of each position vector is 6770 km. WebApr 24, 2024 · Converting the position to spherical coordinates is straightforward: r = √x2 + y2 + z2 θ = atan2(y, x) ϕ = arccos(z / r) (From http://dynref.engr.illinois.edu/rvs.html) However, velocity eludes me, despite having the equation written in front of me.

WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. WebThe formula to determine the position vector from A to B is AB = (x k+1 - x k, y k+1 - y k). The position vector AB refers to a vector that starts at point A and ends at point B. …
