Final answer:

To calculate the final velocity of a train with an initial velocity of 44 m/s and an acceleration of -4 m/s², use the equation Vf = Vi + at.

Step-by-step explanation:

Given that a train has an initial velocity of 44 m/s and an acceleration of -4 m/s², we can calculate its final velocity using the equation:

Vf = Vi + at

Where:

Vf = final velocity

Vi = initial velocity

a = acceleration

t = time

Plugging in the values, we have:

Vf = 44 + (-4)t

To find the final velocity, we need the value of 't'. If you provide the time, we can calculate the final velocity.

Complete question:

A train has an initial velocity of 44m/s and an acceleration of -4m/s². calculate its velocity​ after 10s ?

Answer:

the final velocity of the train is 4 m/s.

Step-by-step explanation:

Given;

initial velocity of the train, u = 44 m/s

acceleration of the train, a = -4m/s² (the negative sign shows that the train is decelerating)

time of motion, t = 10 s

let the final velocity of the train = v

The final velocity of the train is calculated using the following kinematic equation;

v = u + at

v = 44 + (-4 x 10)

v = 44 - 40

v = 4 m/s

Therefore, the final velocity of the train is 4 m/s.
