Answer:

600m/s

Explanation:

From the first condition, applying the equation:   s =ut+\frac{1}{2} at^{2}

                                                                                  ;where s = displacement

                                                                                               u = initial velocity

                                                                                               a = acceleration

                                                                                                t = time.

We get => (270) = (0)(3)+\frac{1}{2}(a)(3)^{2}

            =>  a=60m/s^{2}

Now, we have time and acceleration and have to find velocity.

Therefore, applying :   v = u+at     ; where v = final velocity

                                                                        u = initial velocity

                                                                        a = acceleration

                                                                         t = time.

We get => v = (0)+(60)(10)

            => v = 600 m/s
