Chapter 36: Q. 46 (page 1060)

Two events in the reference frame Soccur 10msapart at the same point in space. The distance between the two events is2400msin the reference frame S'.

a. What is the time interval between the events in reference frame S'鈥�?

b. What is the velocity of S'relative to S?

Short Answer

Expert verified

a. 12.8渭sis the time interval between the events in the reference frame S'.

b. 480cis the velocity of S'relative toS.

Step by step solution

01

Part (a) step 1: Given Information 

We need to find the time interval between the events in reference frameS'.

02

Part (a) step 2:Simplify

Consider:

鈭�x'=2400mt=10脳10-6s

Now, finding the time interval between the events in the reference frameS'

鈭�t2=c鈭�t2-鈭�x2=c鈭�t'2-鈭�x'2c鈭�t'2=c脳10脳10-62+24002c鈭�t'2=3,02脳106+2.42脳106c鈭�t'2=3.02+2.42脳106c鈭�t'2=3.841脳103鈭�t'=3.841脳1033脳108鈭�t'=12.8渭s

03

Part (b) step 1: Given Information

We need to find the velocity of S'relative to S.

04

Part (b) step 2: Simplify

The velocity of S'relative to S

At t=1.0s, a firecracker explodes at x=10min reference frame S. Four seconds later, a second firecracker explodes at x=20m. Reference frame S鈥� moves in the x-direction at a speed of 5.0m/s. What are the positions and times of these two events in frame S鈥�?

Some particle accelerators allow protons1p+2and antiprotons1p-2to circulate at equal speeds in opposite directions in a device called a storage ring. The particle beams cross each other at various points to causep++p-collisions. In one collision, the outcome isp++p-鈫�e++e-+纬+纬, where g represents a high-energy gamma-ray photon. The electron and positron are ejected from the collision at0.9999995cand the gamma-ray photon wavelengths are found to be1.0脳10-6nm. What were the proton and antiproton speeds, as a fraction of c, prior to the collision?

A 1.0g particle has momentum 400,000kgm/s. What is the particle鈥檚 speed in m/s?

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?

On a futuristic highway, a 15mlong rocket travels so fast that a red stoplight, with a wavelength of 700nm, appears to the pilot to be a green light with a wavelength of 520nm. What is the length of the rocket to an observer standing at the intersection as the rocket speeds through?
