Chapter 2, Problem 1Q
Michelson used the motion of the Earth around the sun to try to determine the effects of the ether. Can you think of a more convenient experiment with a higher speed that Michelson might have used in the 1880s? What about today?
Expert Solution & Answer
To determine
Chances of convenient experiment with a higher speed that Michelson might have used in the
1880s and experiment used in present time.
Answer to Problem 1Q
No, there was no chance to think about a more convenient experiment with a higher speed than Earth in 1880s and in present time higher speed than Earth is possible in hyperloop accelerators.
Explanation of Solution
This is very difficult to think about more convenient experiment with a higher speed that Michelson might have used in the 1880s. At that time Earth was the fastest possible frame. Orbital speed of Earth that is earth orbits sun with a speed about
Michelson who was an ingenious scientist for measuring the phase difference between the light waves, built a device called an interferometer. Direction of the motion of the Earth continuously changes. Due to change in direction of motion observable changes in the Earth’s orbital velocity throughout the year can be seen.
That time there was not any information about the speed of the sun through ether. In present day higher speed than Earth is possible in hyperloop accelerators. You can place whole setup in the accelerator and can observe the fringe pattern. In hyperloop accelerators, with help of low-pressure tube air resistance can be reduced which helps to achieve a higher speed.
Conclusion:
Therefore, it was not possible to more convenient experiment with higher speed in 1880s and today it is possible to get more higher speed than Earth.

A 1.40-kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Figure a). The object has a speed of v₁ = 3.50 m/s when it makes contact with a light spring (Figure b) that has a force constant of 50.0 N/m. The object comes to rest after the spring has been
compressed a distance d (Figure c). The object is then forced toward the left by the spring (Figure d) and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest a distance D to the left of the unstretched spring (Figure e).

As shown in the figure, a 0.580 kg object is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m. When it is released, the object travels along a frictionless, horizontal surface to point A, the bottom of a
vertical circular track of radius R = 1.00 m, and continues to move up the track. The speed of the object at the bottom of the track is VA = 13.0 m/s, and the object experiences an average frictional force of 7.00 N while sliding up the track.

There will be a number of dead-end sidings where single cars can be stored until they are needed. To keep the cars from running off the tracks at the end of the siding, you have designed a combination of two coiled springs as illustrated in the figure below.
