- (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.arrow_forwardOur solar system orbits the center of the Milky Way Galaxy. Assuming a circular orbit 30,000 ly in radius and an orbital speed of 250 km/s, how many years does it take for one revolution? Note that this is approximate, assuming constant speed and circular orbit, but it is representative of the time for our system and local stars to make one revolution around the galaxy.arrow_forwardThe great astronomer Edwin Hubble discovered that all distant galaxies are receding from our Milky Way Galaxy with velocities proportional to their distances. It appears to an observer on the Earth that we are at the center of an expanding universe. Figure 3.64 illustrates this for five galaxies lying along a straight line, with the Milky Way Galaxy at the center. Using the data from the figure, calculate the velocities: (a) relative to galaxy 2 and (b) relative to galaxy 5. The results mean that observers on all galaxies will see themselves at the center of the expanding universe, and they would likely be aware of relative velocities, concluding that it is not possible to locate the center of expansion with the given information. 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.

- 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.arrow_forwardOne strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then, while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is thrown at an angle of 70.0 with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? (b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?arrow_forwardAn ice hockey player is moving at 8.00 m/s when he hits the puck toward the goal. The speed of the puck relative to the player is 29.0 m/s. The line between the center of the goal and the player makes a 90.0° angle relative to his path as shown in Figure 3.65. What angle must the puck's velocity make relative to the player (in his frame of reference) to hit the center of the goal?arrow_forward
- Two cars move with constant velocities. At t = 0, a blue car is at xBo= 20 m. After t = 4 s in the blue car time frame of reference, a red car located then at xRo= 0 m , within 3 seconds catches up with the blue car at xB = xR = 60 m. Find the velocities of blue and red cars.arrow_forwardWhen sailing, the wind feels stronger when you sail upwind (“beating”) than when you are sailing downwind (“running”). Explain.arrow_forwardA dog is running toward a cat that is 1.5 m away. Initially at rest, the cat sees the dog running toward her and accelerates away from the dog at 0.85 m/s/s directly toward a small pet door that is another 1.5 m in front of the cat (too small for the dog, but OK for the cat to fit through). Seeing the small window ahead, the dog (initially moving at 1.6 m/s) begins to slow down at 0.2 m/s/s. We need to figure out if the cat makes it out of the door before the dog arrives, and so how far does the dog go by the time the cat reaches the door? Report your answer to the tenths decimal place.arrow_forward

Neglecting the brief time periods required for the acceleration of the ship during blastoff and turnarounds, find the difference in age between Nora and Allison when they are reunited. difference in age: years Who is younger? They are still the same age. need more information Nora Allisonarrow_forwardIn tennis, one of the primary ways to win a point is by making the ball bounce twice on your opponent's side of the court. A tennis player hits a ball at a velocity of 50 m/s at a 0 degree angle from 1m high. When the ball bounces it reflects its velocity angle perfectly and loses 30% of its speed. How long does the other player have to return the ball before the second bounce?arrow_forward
