    The acceleration of the ball is 5 m/s^2. This can be calculated using a formula that relates the change in velocity, acceleration, and time. This formula is:

    Vf = Vi + at

    where:

    Vf = final velocity

    Vi = initial velocity

    a = acceleration

    t = time

    Substituting the values gives:

    30 = 20 + a (2)

    a = 5 m/s^2 - - > Final Answer
