    Answer:

    200 m

    Explanation:

    Initial velocity- 0

    final velocity= v

    time= 10 seconds

    to find final velocity

    v= u + at

    v= 0 + 4*10

    v= 0 + 40

    v= 40 m/s

    to find distance

    s= ut + 1/2at²

    s= 0*10 + 1/2*4*(10)²

    s= 1/2 *4*100

    s=200m

    answer : 200 m
