    Step-by-step explanation:

    acc. to newtons equations

    v = u + gt ( acceleration = acc. due to garvity )

    v = 0 + 10 x 1

    v = 10 m / s

    the ball will reach the ground at a speed of

    10 m/s

    acc. to second equation

    v^2 = u^2 + 2gs

    100 = 0 + 2 x 10 x s

    100 /20 = s

    s = 5 m

    Step-by-step explanation:

    h=1/2gt²

    h=1/2(10)(2)²

    h=20m

    h=vt

    20=2v

    v=10m/s OK friend
