Suppose we find an Earth-like planet around one of our nearest stellar neighbors, Alpha Centauri (located only 4.4 light-years away). If we launched a "generation ship" at a constant speed of 1500.00 km/s from Earth with a group of people whose descendants will explore and colonize this planet, how many years before the generation ship reached Alpha Centauri? (Note there are 9.46 ××1012 km in a light-year and 31.6 million seconds in a year.
Sam is an astronomer on planet Hua, which orbits the distant star Barnard. It has recently been accepted that Hua is spherical in shape, although its exact size is unknown. While studying in the library, in the city of Joy, Sam learns that during equinox, Barnard is directly overhead in the city of Bar, located 1500.0 km north of his location. On the equinox, Sam goes outside and measures the altitude of Barnard at 83 degrees. What is the radius of Hua in km?
You have a dream you are driving across the country. In your dream, you leave Kala- mazoo at 9 a.m. on a tour along 194: you drive to Chicago, Milwaukee, Minneapolis, and Fargo. You arrive to Fargo at 8 p.m. You spent your entire trip staring out the window enjoying the sights, and (this is a dream, remember?) you didn't get hurt. According to the trip counter on your odometer, you have travelled 813 miles on your trip. The speed limit was between 55 mph and 70 mph on your trip. Were you ever speeding? Explain your reasoning.
