    If we consider air resistance, then in case of a small ball thrown up from the ground correct is

    A) its initial velocity from ground is more than its final velocity on reaching ground

    B) its final velocity on reaching ground is more than its initial velocity

    C) its final velocity on ground is equal to its initial velocity

    D) time to reach maximum height is more than its time of all

    Correct Answer: A

    Solution :

    We can throw a ball up with any velocity but it cannot have velocity greater than its terminal velocity during free fall. So, option [a] is correct. From figure, we have
