Which of the following observers is in an inertial reference frame?
A
A person sitting in a car that is speeding up
B
A person sitting in a car moving at a constant velocity
C
A person sitting in a car that is slowing down
Homework Answers
The observer is in initial reference frame in the B condition in which the observer is sitting in a car and moving at a constant velocity. Whenever we talk about the relativity, the initial frame is the one in which the body goes without any rotation or acceleration. Here in the A and C cases, the body is being accelerated by increasing or decreasing the velocity so that's why we can't consider them a initial frame of reference.

2. Show that the principle of work and energy is valid for observers in any inertial reference frame, by considering the 100-kg block which rests on the smooth surface and is subjected to a horizontal force of 6 N.

This is wrong.
PartI n an inertial frame of reference, a series of experiments is conducted. In each experiment, two or three forces are applied to an object. The magnitudes of these forces are given. No other forces are acting on the object. In which cases may the object possibly move at a constant velocity of 256 m/s? The forces applied are as follows: Check all that apply Hints Hint 1. Using the net force In an inertial frame of...
