Chapter 36: Q. 5 (page 1059)

An out-of-control alien spacecraft is diving into a star at a speed of 1.0脳108m/s. At what speed, relative to the spacecraft, is the starlight approaching?

Short Answer

Expert verified

The speed will be speed of light c.

Step by step solution

01

Given information

we have given,

alien aircraft speed =108m/s

We have to find the speed of the starlight with respect to aircraft.

02

Simplify

We know that light speed will be same for all the inertial frame irrespective to the speed of frame.

it is Einstein's principle of relativity.

so speed of the starlight will be speed of the light c.

In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested traveling at close to the speed of light. Suppose you wish to visit the red giant star Betelgeuse, which is430lyaway, and that you want your 20,000kgrocket to move so fast that you age only 20yearsduring the round trip.

a . How fast, as a fraction of c, must the rocket travel relative to earth?

b. How much energy is needed to accelerate the rocket to this speed?

c. Compare this amount of energy to the total energy used by the United States in the year 2015, which was roughly1.0脳1020J

You are standing at x=9.0km.Lightning bolt 1strikes at x=0kmand lightning bolt 2strikes at x=12.0km. Both flashes reach your eye at the same time. Your assistant is standing at x=3.0km. Does your assistant see the flashes at the same time? If not, which does she see first, and what is the time difference between the two?

You fly 5000kmacross the United States on an airliner at 250m/s.You return two days later at the same speed.

a. Have you aged more or less than your friends at home?

b. By how much?

Hint: Use the binomial approximation

Consider the inelastic collision e-+e-鈫�e-+e-+e-+e+in which an electron-positron pair is produced in a head-on collision between two electrons moving in opposite directions at the same speed. This is similar to Figure 36.39, but both of the initial electrons are moving.

a. What is the threshold kinetic energy? That is, what minimum kinetic energy must each electron have to allow this process to occur?

b. What is the speed of an electron with this kinetic energy?
