    Answer:

    The velocity of the tennis ball is 4.52 m/s.

    Explanation:

    Given that,

    The distance covered by ball, d = 9.5 meters (due south)

    Time, t = 2.1 sec

    Let v is the velocity of the tennis ball. We know that the velocity of an object is given by the total distance covered divided by total time taken. It is given by :

    v=\dfrac{d}{t}\\\\v=\dfrac{9.5\ m}{2.1\ s}\\\\v=4.52\ m/s

    So, the velocity of the tennis ball is 4.52 m/s. Hence, this is the required solution.
