Our two intrepid relacar drivers are named pam and ned. we use these names to make it easy to remember: measurements made by pam are primed (x', t') and those made by ned are not primed (x, t). v is the velocity of pam (the other frame of reference) as measured by ned. what is the interpretation of v'?

there are 4 possible choices for this

a. the velocity of pam as measured by ned.
b. the velocity of pam as measured by pam.
c. the velocity of ned as measured by ned.
d. the velocity of ned as measured by pam.

The velocity of Ned as measured by Pam is the interpretation of v.

Option D

Explanation:

According to question, we know that this is an issue depending on the logical and translation of the factors. From the measured information taken what is gathered by the two people is communicated and we have given as:

The Ned reference framework : (x, t)  

The Pam reference framework :  

From the reference framework, we realize that ν is the speed of Pam (the other reference framework) as estimation by Ned.  

At that point, is the speed of Ned (from the other arrangement of the reference) as estimation by Pam.

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
