Chapter 36: Q. 7 (page 1059)

Your job is to synchronize the clocks in a reference frame. You are going to do so by flashing a light at the origin at t=0s. To what time should the clock at (x,y,z)=(30m,40m,0m) be preset?

Short Answer

Expert verified

The time is166.6ns.

Step by step solution

01

Given information

We have given,

(x,y,z)=(30m,40m,0m)

We have to find the time in the clock at that position.

02

Simplify

The distance will travel,

R=x2+y2+z2R=(30)2+(40)2+0R=900+1600R=2500R=50m/s

Since, the speed will speed of the light c.

Then time taken for the light to travel,

t=RV=50m/s3脳108m/st=166.6ns

Two rockets are each 1000mlong in their rest frame. Rocket Orion, traveling at 0.80c relative to the earth, is overtaking rocket Sirius, which is poking along at a mere 0.60c. According to the crew on Sirius, how long does Orion take to completely pass? That is, how long is it from the instant the nose of Orion is at the tail of Sirius until the tail of Orion is at the nose of Sirius?
