Question

105. Comet Halley will be travelling about 1.5 km/s (almost 1 mile per second) in 2023 when it reaches aphelion. When it reaches perihelion in 2061, it will be sixty times closer to the Sun, so its speed will be about: (conserve angular momentum) a. 1.5 km/s b. 90 km/s c. 5400 km/s d. 0.025 km/s e. 0.0004 km/s
