Question

a car moves with initial velocity of 25m/s to the north,If an acceleration of 3m/s to the south acts on it, then its velocity after 6 s wil be what

Answer 1

Answer:

given that:

initial velocity, u=25m/s

acceleration, a=3m/s²

t=6s

find:

final velocity, v=?

a=(v-u) /t

3=(v-25) /6

18=v-25

v=43m/s
