Explanation The expansion of the universe results in the increase in the distance between all the points of the universe. The distance of all the galaxies increases from one another. The distance of the galaxy becomes double of their initial value if the universe expands to its double area. The rate of expansion of the universe as shown by the graphs in the figure shows the relation between the velocities of the galaxies moving away from the one another as the distance between the galaxies increases. The slope of the graph shows the rate of expansion of the universe. The slope of the graph is maximum in the figure 3 . In this, the velocities of the galaxies will be high at smaller distances also

9. Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .15 seconds. Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.

In the movie Fast X, a 10100 kg round bomb is set rolling in Rome. The bomb gets up to 17.6 m/s. To try to stop the bomb, the protagonist Dom swings the counterweight of a crane, which has a mass of 354000 kg into the bomb at 3.61 m/s in the opposite direction. Directly after the collision the crane counterweight continues in the same direction it was going at 2.13 m/s. What is the velocity (magnitude and direction) of the bomb right after the collision?
