You have been transported into the future and are enrolled in your preferred college, majoring in the subject of your dreams, But all is not well. You have been kidnapped by armed political science majors (who are upset because you told them that
political science is not a real science)
Although blindfolded, you can tell the speed of their car (by the whine of the engine) and the time of travel (by mentally
counting off seconds). You can also tell that they have only been driving in one direction since they have taken no turns while
traveling. From these clues, you know that you are taken along the following course: 32 km/h for 15 minutes, 60 km/hr for 30
minutes, 16 km/hour for 15 minutes. At that point, how far away are you from your initial position mi

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
