Find the time taken, if the speed of a train increased from 72 km/hr to 90 km/hr for 234 km. leave your answer in seconds

Time taken = 10400 s

Explanation:

Given:

Initial speed of the train,

Final speed of the train,

Displacement of the train,

Using Newton's equation of motion,

Now, using Newton's equation of motion for displacement,

Now, plug in the value of in the above equation. This gives,

Now, plug in 234000 m for , 25 m/s for and 20 m/s for . Solve for .

Therefore, the time taken by the train is 10400 s.

it is a negative acceleration

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
