    Answer:

    d = 8 m

    Explanation:

    Given that,

    Initial speed, u = 0

    Final speed, v = 4 m/s

    Time, t = 4 s

    We need to find the distance traveled by a bike. Let it is equal to d. Using second equation of kinematics as follows :

    d=ut+\dfrac{1}{2}at^2\\\\\text{a=acceleration of bike and u = 0}\\\\d=\dfrac{1}{2}\times \dfrac{v-u}{t}\times t^2\\\\d=\dfrac{(v-u)t}{2}\\\\d=\dfrac{(4-0)4}{2}\\\\d=8\ m

    So, the car cover a distance of 8 m.
