As Halley’s comet orbits the sun, its distance from the sun changes dramatically. If the comet’s speed at a distance of 9.8 × 1010 m from the sun is 5.3 × 104 m/s and angular momentum is conserved, what is its speed when it is 3.6 × 1012 m from the sun? Assume the comet can be treated as a point mass. Ignore radial components of momentum

The speed of comet is 1442.77 m/s.

Explanation:

Given that,

Speed of comet's

Distance from the sun

Distance

We need to calculate the speed of comet

Using conservation of angular momentum

Here.

Put the value into the formula

Hence, The speed of comet is 1442.77 m/s.
