Earth has its own atmosphere. That is one reason all the water that has been on Earth has been recycled through the water cycle. It never leaves Earth’s atmosphere.
Answer:
true can i get brainliest :)
Explanation:
Answer:
-3044.848m/s^2
Explanation:
Initial velocity = 15.7 m/s (u)
Final velocity = -14.444 m/s (v) velocity after striking moving opposite direction.
Time = 0.0099 s
Average acceleration :
change in velocity/ total time
= V - U/t
= -14.444 m/s - 15.7 m/s/0.0099 s
= -30.144/0.0099 s
= -3044.848m/s^2
Answer:
Acceleration will be 
Explanation:
We have given that car is traveling with speed 34 miles per hour
So initial speed of the car u = 34 miles per hour
After 2 hour speed will be 84 miles per hour
So final speed V = 84 miles per hour
Time = 2 hour
From first equation of motion we know that 
So acceleration
