Answer:
Accelaration = 2 m/s
Average velocity= 10m/s
total distance = 100 m
Explanation:
final velocity = 72 km/h or 20 m/s
For accelaration,
v= u+ at
20 = 10 a
a = 2 m/s
For total distance travelled,
s = ut+ 1/2 at^2
s= 1/2 (2) (10)^2
s= 100 m
For average velocity,
average velocity = total displacement/
total time
average velocity = 100/10
= 10 m/s

Answer:
The Universe is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. ... The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty.
