By definition,
Distance = Speed * Time
Therefore the distance traveled is
(7 m/s)*(20 s) = 140 m
Answer: 140 m
Answer:
The object displacement is 0 meters.
Explanation:
Because the expression for the object position as function of time is:

At t= 3.0=t2 seconds the x-position of the object is:


and at t=1.0=t1 seconds the x-position of the objects is:


The total displacement (
) of the object between t2 and t1 is the difference between x(3.0s) and x(1.0s):


The displacement of the object is zero!!!
The Earth and the Moon circle their common center of mass, and
that common center of mass is what circles the Sun, once a year.
