This is a challenging problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values.
Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check
your calculations!
This problem is closely related to the spectacular impact of the comet Shoemaker-Levy with Jupiter in July 1994. (More information
about the event can be found here.)
A rock far outside a solar system similar to ours is initially moving very slowly relative to its sun, in the plane of the orbit of a large
planet (about the size of Jupiter) around its sun. The rock falls toward the sun, but on its way to the sun it collides with the planet. The
mass of the planet is 4 x 1027 kg, the mass of its sun is 3.2 x 1030 kg, the radius of the planet is 1.4 x 10® m, and the center-to-center
distance from the planet to the sun is 9.2 x 1011 m.
Part 1
(a) Calculate the rock's speed just before it…
Tutorial
Based on the orbital properties of Uranus, how far across the sky in arc seconds does it travel in one Earth
day? The average orbital radius is 2.88 x 109 km and the period is 84.0 years. (Assume Uranus and the Earth
are at the closest point to one another in their orbits.)
How many full Moons does this distance cover if the Moon has an angular diameter of 0.5 degrees?
Part 1 of 4
We first need to determine how fast the planet is moving across the sky. If we know the period and the
distance between the Sun and the planet we can calculate the velocity using:
2ar
which will tell us how many kilometers the planet travels in a day if we convert the period into days.
