Chapter 36: Q. 12 (page 1059)

You are flying your personal rocket craft at 0.90cfrom Star Atoward Star B. The distance between the stars, in the stars’ reference frame, is 1.0ly. Both stars happen to explode simultaneously in your reference frame at the instant you are exactly halfway between them. Do you see the flashes simultaneously? If not, which do you see first, and what is the time difference between the two?

Short Answer

Expert verified

1.)I am at rest in my frame.

2.)The explosions are about the same distance apart.

3.)The speed of light is c,all light will arrive at the same time.

Step by step solution

01

Given Information

We have given that,

You are flying your personal rocket craft at 0.90cfrom Star Atoward Star B.

The distance between the stars, in the stars’ reference frame, is 1.0ly.

02

Simply

0.90cfrom Star Atoward Star B,and the distance between the stars is 1.0ly.

Star Ais moving away from me and Star Bis moving toward me in my frame.

Both stars erupt at the same time when I am exactly halfway between them.

The flashes from the two stars travel toward me with speed c.Since,

1.)I am at rest in my frame.

2.)The explosions are about the same distance apart.

3.)The speed of light is c,all light will arrive at the same time.

As the meter stick in FIGURE Q36.8 flies past you, you simultaneously measure the positions of both ends and determine that L<1m.

a. To an experimenter in frame S′, the meter stick’s frame, did you make your two measurements simultaneously? If not, which end did you measure first? Explain.

b. Can experimenters in frame S′ give an explanation for why your measurement is less than 1 m.

A 30-m-long rocket train car is traveling from Los Angeles to New York at 0.50c when a light at the center of the car flashes. When the light reaches the front of the car, it immediately rings a bell. Light reaching the back of the car immediately sounds a siren.

a. Are the bell and siren simultaneous events for a passenger seated in the car? If not, which occurs first and by how much time?

b. Are the bell and siren simultaneous events for a bicyclist waiting to cross the tracks? If not, which occurs first and by how much time?
