Answer:4.674hours
Step-by-step explanation:
1hr-89tons
24hrs-xtons
X=24×89
X=2136tons
24hrs-2136tons
Yhr-416tons
Y=24×416\2136
Y=4.674hrs
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:
f=2/6
Step-by-step explanation:
Write an equation
f/(-2/3)=-1/3
Solve
f=(-1/3)*(-2/3)
f=2/6
The rules of significant figures are: 1. all non zeros are significant. 2. trailing zeros are significant. 3. zeros between non-zeros are signifincant. Hence, applying these to the given.
