16. Over a time interval of 2.16 years, the velocity of a planet orbiting a distant star reverses direction, changing from +20.9 km/s to – 18.5 km/s. Find (a) the total change in the planet's velocity (in m/s) and (b) its average acceleration (in m/s²) during this interval. Include the correct algebraic sign with your answers to convey the directions of the velocity and the acceleration.

Explain why, when defining the length of a rod, it is necessary to specify that the positions of the ends of the rod are to be measured simultaneously.
When Sedna was discovered in 2003, it was the most distant object known to orbit the Sun. Currently, it is moving toward the inner solar system. Its period is 10,500 years. Its perihelion distance is 75 AU. a. What is its semimajor axis in astronomical units? b. What is its aphelion distance?
Unreasonable Results Suppose you wish to shoot supplies straight up to astronauts in an orbit 36,000 km above the surface of the Earth. (a) At what velocity must the supplies be launched? (b) What is unreasonable about this velocity? (c) Is there a problem with the relative velocity between the supplies and the astronauts when the supplies reach their maximum height? (d) Is the premise unreasonable or is the available equation inapplicable? Explain your answer.
Review. In 1963, astronaut Gordon Cooper orbited the Earth 22 times. The press stated that for each orbit, he aged two-millionths of a second less than he would have had he remained on the Earth. (a) Assuming Cooper was 160 km above the Earth in a circular orbit, determine the difference in elapsed time between someone on the Earth and the orbiting astronaut for the 22 orbits. You may use the approximation 11x=1+x2 for small x. (b) Did the press report accurate information? Explain.
An astronaut, whose mission is to go where no one has gone before, lands on a spherical planet in a distant galaxy. As she stands on the surface of the planet, she releases a small rock from rest and finds that it takes the rock 0.580 ss to fall 1.90 mm. Part A If the radius of the planet is 9.50×107m9.50×107m, what is the mass of the planet? Express your answer with the appropriate units. mpmp = nothingnothing

The mean distance of Mars from the Sun is 1.52 times that of Earth from the Sun. From Kepler’s law of periods, calculate the number of years required for Mars to make one revolution around the Sun; compare your answer with the value given in Appendix C.
In 2015, the U.S. national debt was about $18 trillion.(a) If payments were made at the rate of $1 000 per second,how many years would it take to pay off the debt, assumingthat no interest were charged? (b) A dollar bill is about 15.5cm long. If 18 trillion dollar bills were laid end to end aroundthe Earth’s equator, how many times would they encirclethe planet? Take the radius of the Earth at the equator to be6 378 km. (Note: Before doing any of these calculations, try toguess at the answers. You may be very surprised.)
A seagull flies at a velocity of 9.5 m/s relative to the air straight into the wind. vSA = 9.5 m/st = 24 mind = 5.6 km a)If it takes the bird 24 min to travel 5.6 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive. b) If the bird turns around and flies with the wind, how long, in minutes, will it take to return 5.6 km?
