Answer to Problem 1VSC

Solution:

At the point A, the expansion of the universe is accelerating.

Explanation of Solution

Introduction:

The expansion of the universe happens with the change in the time. The distance between two points increases. This is due to the expansion of space-time. The scale of space-time fabric itself changes. This expansion is given by four models namely, re-collapsing universe, critical universe, coasting universe, and accelerating universe as shown in the figure.

The Cosmic Perspective (8th Edition), Chapter 23, Problem 1VSC

Point A is a time in future. At point A, the expansion of the universe is accelerating. The two distant points in the universe would be moving farther apart. The scale of the space-time fabric was expanding. The galaxies would be moving apart more rapidly. The gravitational force would not be strong enough to decelerate or stop expansion.

Conclusion:

Point A represents the accelerated expansion of universe in future.

You are working with a team that is designing a new roller coaster-type amusement park ride for a major theme park. You are present for the testing of the ride, in which an empty 150 kg car is sent along the entire ride. Near the end of the ride, the car is at near rest at the top of a 100 m tall track. It then enters a final section, rolling down an undulating hill to ground level. The total length of track for this final section from the top to the ground is 250 m. For the first 230 m, a constant friction force of 370 N acts from computer-controlled brakes. For the last 20 m, which is horizontal at ground level, the computer increases the friction force to a value required for the speed to be reduced to zero just as the car arrives at the point on the track at which the passengers exit. (a) Determine the required constant friction force (in N) for the last 20 m for the empty test car. N (b) Find the highest speed (in m/s) reached by the car during the final section of track length…
A player kicks a football at the start of the game. After a 4 second flight, the ball touches the ground 50 m from the kicking tee. Assume air resistance is negligible and the take-off and landing height are the same (i.e., time to peak = time to fall = ½ total flight time). (Note: For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers. Provide answer to 2 decimal places unless stated otherwise.)
