Explanation:
<h3><u>Question</u><u>:</u></h3>
A racing car is travelling at 70 m/s and accelerates at -14 m/s^2. What would the car’s speed be after 3 s?
<h3><u>Statement:</u></h3>
A racing car is travelling at 70 m/s and accelerates at -14 m/s^2.
<h3><u>Solution</u><u>:</u></h3>
- Initial velocity (u) = 70 m/s
- Acceleration (a) = -14 m/s^2
- Time (t) = 3 s
- Let the velocity of the car after 3 s be v m/s
- By using the formula,
v = u + at, we have

- So, the velocity of the car after 3 s is 28 m/s.
<h3><u>Answer:</u></h3>
The car's speed after 3 s is 28 m/s.

Given data:
Yan speed;

Christopher speed;

Christophe starts 30 s later than Yan. Therefore, Christophe takes 30 s less than Yan to reach the same distance.
Part (A)
The distance is given as,

Let both Yan and Christophe meet at d distance from the start position. Therefore,

Substituting all known values,

Therefore, 600 s after Yan's departure Christophe will join him.
Part (B)
The distance is given as,

Substituting all known values,

Therefore, Christophe joins Yan after 6.17 km from the start.
They’re at a velocity of 2.0 m/s
I'm guessing that the purpose of the article is to inform the
general public of the work that these Physicists did when they
attempted to detect the existence or non-existence of telepathy
in a controlled, scientifically acceptable setting.
The REASON the article was ever presented in a non-professional
publication was most likely in deference to the general public's interest
in telepathy, UFOs, aliens, flat Earth, Astrology, and all other forms of
weird garbage. In other words, its publication was motivated more by
the desire to sell magazines than by any inclination to impart any real,
useful information to the general public.
