leitkurve F=(mv^2)/r

Lösung

leitkurve

F = \frac{m v ^{2}}{r}

Lösung

r = - \frac{1}{4 m}

Schritte zur Lösung

Rewrite

F - \frac{m v ^{2}}{r} = 0

in the standard form

4 \cdot \frac{1}{4 m} (r - 0) = (v - 0)^{2}

(h, k) = (0, 0), p = \frac{1}{4 m}

Parabola is symmetric around the y-axis and so the directrix is a line parallel to the x-axis, a distance

- p

from the center

(0, 0)

y-coordinate

r = 0 - p

r = 0 - \frac{1}{4 m}

Fasse zusammen

r = - \frac{1}{4 m}
