Freight trains can produce only relatively small accelerations and decelerations. what is the final velocity of a freight train that accelerates at a rate of 0.71 m/s2 for 3.85 min, starting with an initial velocity of 4.6 m/s? keep 2 decimal places.

Final speed of the train, v = 168.61 m/s

Explanation:

It is given that,

Acceleration of the train,

Time taken, t = 3.85 min = 231 s

Initial velocity of the train, u = 4.6 m/s

We need to find the final velocity (v) of the train. It can be calculated using first equation of motion as :

v = 168.61 m/s

So, the final velocity of the train is 168.61 m/s. Hence, this is the required solution.
