## Homework Statement

consider the motion of a comet in an elliptical orbit around a star. the eccentricity of the orbit is given by e= 0.20 and the distance between the perhelion and the aphelion is 1.0 × 10^power8

a- find the distances of nearest and farthest approaches of the comet.

b- if the speed of the comet is 81 km/s at perihelion, what is its speed at aphelion?

there is a solution but i cant understand it

i hope someone help me step by step
