Question

Hello all. A comet goes around the sun in an elliptical orbit. At itsfarthest point, 395million miles from the sun, it is traveling witha speed of 15, 175 mi/h. How fast is it traveling at its closestapproach to the sun, at a distance of 200 millionmiles?__________mi/h An asteroid in an elliptical orbit about the sun travels at3.1 x 10^6 m/s at perihelion ( the point of closest approach) at adistance of 3.8 x 10^8 km from the sun. How fast is it traveling ataphelion ( the most distant point), which is 9.0 x 10^8 km from thesun?______________m/s Hello all. A comet goes around the sun in an elliptical orbit.

Explanation / Answer

By using the conservation of angular momentum M=2*1030 kg 395*15175=200*v2 => v2=29971mi/h (b)similarly, 3.1 x 10^6*3.8 x 10^8 km =v2*9.0 x 10^8 km =>v2=1.31*106 m/s (b)similarly, 3.1 x 10^6*3.8 x 10^8 km =v2*9.0 x 10^8 km =>v2=1.31*106 m/s
