Question:

At the point in its orbit when it is closest to the Sun, Halley€™s Comet moves with a speed of 54,500 m/s (Figure 3.48). When it is at its most distant point, the separation between it and the Sun is about 60 times larger than when it is at its closest point. What is the speed of the comet at the distant point?
