Answer:
Use the AU formula
Explanation:
1 astronomical unit = 149597871 kilometer
Yes, this is accurate. While "dark matter" might exist, it is still more of a theory, it is not yet defined properly. As far as we truthfully know, the entire universe is just matter and energy.
It is given that u=36km/h
V= 72km/h
We have to convert it into m/s ao we will multiply it with 5/18
U=36×5/18=10
V=72×5/18=20
So acceleration =v-u/t
= 20-10/t
The time will be 9:45-9:25=20min
So we will convert it into second
= 20×60
a=20-10/20×60
=10/20×60
1/120
From newtons 2nd law
V^2-u^2=2as
S=v^2-u^2/2a
=400-100×120/2
=18000m/s
