. When we estimate distances from velocity data, it is some- times necessary to use times fo, f1, fz, fz, ... that are not equally spaced. We can still estimate distances using the time periods At; = ti – ti-1. For example, on May 7, 1992, the space shuttle Endeavour was launched on mission STS-49, the purpose of which was to install a new perigee kick motor in an Intelsat communications satellite. The table, provided by NASA, gives the velocity data for the shuttle between liftoff and the jettisoning of the solid rocket boosters. Use these data to estimate the height above the earth's surface of the space shuttle Endeavour, 62 seconds after liftoff.

(a) Use the distance and velocity data in Figure 3.64 to find the rate of expansion as a function of distance. (b) If you extrapolate back in time, how long ago would all of the galaxies have been at approximately the same position? The two parts of this problem give you some idea of how the Hubble constant for universal expansion and the time back to the Big Bang are determined, respectively. Figure 3.64 Five galaxies on a straight line, showing their distances and velocities relative to the Milky Way (MW) Galaxy. The distances are in millions of light years (Mly), where a light year is the distance light travels in one year. The velocities are nearly proportional to the distances. The sizes of the galaxies are greatly exaggerated; an average galaxy is about 0.1 MlY across.
(a) A car speedometer has a 5% uncertainty. What is the range of possible speeds when it reads 90 km/h? (b) Convert this range to miles per how. Note 1 km = 0.6214 mi.
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?
What value is the acceleration of 45 microns/min2 in the units of nm per seconds squared?
A Global Positioning System (GPS) receiver is a device thatlets you figure out where you are by receiving timed radio signals from satellites. It works by measuring the travel time for the signals, which is related to the distance between you and the satellite. By finding the ranges to several different satellites in this way, it can pin down your location in three dimensions to within a few meters. How accurate does the measurement of the time delay have to be in units of nanoseconds to determine your position to 10 m accuracy? 1 s = 10^9 ns
i need the answer quickly
Please solve correctly!! Thank you

Coyote happens to be chasing after the Roadrunner, who is traveling in the +x-direction with a constant velocity of 8.72 m/s. Wile E. Coyote has a velocity of +3.28 m/s and a constant acceleration of +2.30 m/s? at the moment it is 10.0 m behind the Roadrunner. Take the initial position of the Roadrunner to be the origin (x = 0). a) time. Hint: Your answer should look like xR = fR(t). Express the final position of the Roadrunner (with respect to the origin) as a function of b) time. Hint: Again, your answer should look like xc = Express the final position of Wile E. Coyote (with respect to the origin) as a function of fc(t). c) use the quadratic formula here, you should get two times. Consider which one, if both, of these times makes sense in the context of this problem. How much time elapses before Wile E. Coyote catches the…
Joey starts riding his scooter from his apartment to campus. He thinks it would be fun to make a graph ofhis position relative to time. By a weird coincidence, the graph is perfectly modeled by the equation 3t^2 -5t + 6 He tells his friend Andie that his average velocity for the second half of his trip was 39.2 units per timeinterval, because the slope formula says to do (256 - 60)/(5 -10) Is Joey correct?
