Transcribed Image Text:A star of mass M = 1.81 x 1030kg is the origin of a coordinate system.
A comet of mass m = 7.87 × 10¹2 kg is initially at location = 2.49 x 10¹5 mî +3.88 × 10¹¹mj. The comet is travelling with velocity 7 = 3.68 × 10³
(The input below will accept answers with no more than 1% variation from the correct value.)
Using conservation of energy and of angular momentum, what is the comet's distance from the star at the instant it's closest, and what is the comet's speed? (Hint: Consider the direction of the velocity relative
to the position when the comet is at its closest point.)
