A spaceship travels at a constant speed from earth to a planet orbiting another star. When the spacecraft arrives, 14 years have elapsed on earth, and 9.9 years have elapsed on board the ship. How far away (in meters) is the planet, according to observers on earth?

The Voyager 1 spacecraft has traveled farther than any other man-made object, and inAugust 2012 it entered into interstellar space when it was a distanceof 1.8 * 1013 m from Earth. How many hours elapsed between thetime a command was sent from Earth and the time the commandwas received by Voyager when it entered interstellar space?

1. Voyager rocket is traveling between Earth and Jupiter (distance  8.013x1010 m). If Voyager probe was thousand times faster and had a speed of v=17x106 m/s=0.057c calculate the Earth-Jupiter distance that instruments aboard measure.  a. What is the time of Voyager's trip measured by instruments onboard? Write your answer in seconds rounded to a whole number (for example 1234 s).   _______________  b. What is the time of the trip measured by NASA on Earth?   2. An asteroid is traveling from asteroid belt to Earth with a speed of 0.6 c. To save the Earth, group of brave men set an explosive device to explode in 138 minutes. When will the group of scientists that monitor asteroid on Earth see the explosion (if everything goes right

Many people have some sense for the SI units describing mass, length, and time. one kilogram is roughly the mass of a typical sports water bottle (when full) one meter is roughly the height of a kitchen counter one second is a typical time interval between heartbeats (when at rest) But the momentum unit we just learned—the "kilogram meter per second"—is another matter! How many kg · m/s might describe the following everyday phenomena? (Recall that momentum equals the product of mass and velocity.) a 0.05 kg (50-gram) tennis ball crossing the court at 20 m/s (about 45 mph) _____________ kg · m/s a 50 kg (110-pound) teenager jogging at 2 m/s    about 4 1 2  mph   .  _______________kg · m/s a two-ton SUV (2,000 kg) following a dirt road at 5 m/s (about 11 mph).  ________________kg · m/s
