Question

    A body is thrown upward with an initial velocity of

    20m/s. How much time will it take to reach its maximum height. (g=10m/s)
    A 1s Correct Answer Incorrect Answer
    B 2s Correct Answer Incorrect Answer
    C 3s Correct Answer Incorrect Answer
    D 4s Correct Answer Incorrect Answer
