urgently need help on gravitation only one part
Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 7.0 x 10^4 m/s when at a distance of 2.5 x 10^11 m from the center of the sun, what is its speed when at a distance of 9.0 * 10^10 m?
___________ m/s
Attempt
(7.0 x 10^4)(2.5 x 10^11)= v(9.0 * 10^10)
v = 194444.444
However, this answer was marked wrong.
