a train has a velocity of 44 metre per second and an acceleration of 4 metre per second square. its velocity after 10 seconds is what

Acceleration=Final velocity-Initial velocity / time.

Acceleration=a=4m/s².

Initial velocity = u = 44m/s

Final velocity=v = let it be v, since we are to look for the final velocity.

Time=t=10seconds.

Mathematically:

a=v-u/t

Substituting the givens into the equation.

4=v-44/10

cross multiply.

4*10 = v-44

40=v-44

40+44=v

v=84m/s
