Answer:
Zero
Explanation:
Average velocity is given by:
where
d is the displacement of the trip
t is the time it takes for the trip to complete
In this problem, the net displacement of the swimmer is zero. In fact:
- First, he swims 30.0 m in the north direction
- Then, he travels back (-30.0 m) in the south direction, to the starting position
Since the final position is equal to the starting position, the displacement is zero:
d = 0
And therefore, the average velocity is also zero.
Answer:
<h3>The answer is 150 m</h3>
Explanation:
In order to find the distance covered we use the formula
<h3>distance = velocity × time</h3>
From the question
velocity = 3 m/s
time = 50 s
We have
distance = 3 × 50
We have the final answer as
<h3>150 m</h3>

<span>According
to the special theory of relativity, all laws of nature
are the same in
reference frames that move at constant speeds.
That means that there's no test or measurement you can do to
detect whether you're moving at a constant speed</span> or how fast.
And THAT means that there's no such thing as "who's REALLY
moving" and "who's REALLY at rest". There's no such thing as
"real" motion, only motion relative to something else.
Most likely it will reflect off the surface and create a fire
