Answer:
The train will travel 493.817 meters until it stops completely.
Step-by-step explanation:
In this case, we know that train applies the brakes and decelerates at constant rate until rest is reached after travelling an unknown distance. Travelled distance (
), measured in meters, can be found by using this kinematic formula:
(Eq. 1)
Where:
- Initial speed, measured in meters per second.
- Final speed, measured in meters per second.
- Acceleration, measured in meters per square second.
Now travelled distance is cleared within the formula:
If we know that 
, 
and 
, then the distance travelled by the train is:
The train will travel 493.817 meters until it stops completely.
Answer:
1.753418e+17
Step-by-step explanation:
To solve q+(-9)=12 we do the following.
q+(-9)=12
+9 +9
q=21
Giving us are end answer of q=21.
Hope this helps!=)
Answer:
3x^2+6x+4 is the answer :D
The slope is 2 because remember, y= mx+b
m= slope
the slope is always multiplied by x
