Question

The New Horizons spacecraft was launched toward Pluto in 1/2006 at the highest velocity of any craft sent into space from Earth - 36,000 mph (10 mi/s). By the time NH reached Jupiter 13 months later, the craft was moving at 50,000 mph (13.9 mi/s). NH will arrive at Pluto in 2015, having taken 9.5 years to travel 33 AU. After the sun, the closest star - Proxima Centauri is 4.2 light years from Earth. How long will it take us to travel to our nearest stellar neighbor at 50,000 mph? Round travel time to the nearest thousandth of a year. Show all your work. A. This, 4.2 ly = AU and B. Travel time to Proxima Centauri = years.
