What is the uniform acceleration that causes a train’s velocity to change from 25 m/s to 75 m/s in an 5.0-s period?

a. 20 m/s2
b. 5 m/s^2
c. 10 m/s2
d. 15 m/s^2

Acceleration of the train is

Explanation:

It is given that,

Initial speed of the train, u = 25 m/s

Final velocity of the train, v = 75 m/s

Time taken, t = 5 s

Charge in speed,

Acceleration of the train is given by change in speed per unit time. It is given by :

So, the acceleration of the train is . So, the correct option is (c).

neither accurate nor precise.
