The orbit of a 1.5 ✕ 1010 kg comet around the Sun is elliptical, with an aphelion distance of 33.0 AU and perihelion distance of 0.850 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to the Earth = 1.496 ✕ 1011 m.) (a)What is its orbital eccentricity? (b)What is its period? (Enter your answer in yr.) (c)At aphelion what is the potential energy (in J) of the comet—Sun system?

The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...

009 10.0 points As Halley's comet orbits the sun, its distance from the sun changes dramatically. If the comet's speed at a distance of 9.1 x 1010 m from the sun is 5.1 x 104 m/s and angular momentum is conserved, what is its speed when it is 3.6 x 1012 m from the sun? Ignore radial components of momentum. Answer in units of m/s.

A comet orbits the Sun and loses mass at a constant rate of
30,000kg/s. The only force acting on the comet is the gravitational
force.
a) From the definition of torque in terms of angular momentum,
torque=dL/dt, show that
dI/dt=-alphaI/omega (alpha= angular acceleration, omega=angular
velocity)
b) The quantity omega/omega(with a dot on it), where (omega with
a dot on it=domega/dt) is a natural time scale for the system's
change in angular frequency (to see this, think about the units).
