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.

a.) is the correct answer.
