What is its speed when it is farthest from the sun if angular momentum is conserved?
As Halley’s comet orbits the sun, its distance from the sun changes dramatically, from 89800000000 m to 5787000000000 m. If the comet’s speed at closest approach is 57710 m/s, what is its speed when it is farthest from the sun if angular momentum is conserved?
