The orbit of Halley's comet around the Sun is a long thin ellipse. At its aphelion (point farthest from the Sun), the comet is 5.3 x 1012 m from the Sun and moves with a speed of 10.0 km/s. What is the comet's speed at its perihelion (closest approach to the Sun) where its distance from the Sun is 8.9 x 1010 m. The mass of the Sun is 1.989 x 1030 kg.
55 km/s
11 km/s
22.5 km/s
110 km/s

Fg = 3.8*1015 N
Fg = 2.8*10-42 N
Fg = 1.6*1021 N
Fg = 4.6*10-75 N
