Question

The train has a intial velocity 44m/s and an acceleration of -4m/s2. Its velocity after 10 second is

Answer 1

here is ur answer plz mark as brainlist

Answer 2

u = 44 m/s

a = -4 m/s^2

t = 10 sec

Therefore, v = u + at

                  v = 44 + (-4) * 10

                  v = 44 - 40

                  v = 4 m/s
