  • A body is dropped from a certain height.

    A
    the time taken to travel first half of the height is greater than that for second half.
    B
    time time taken to travel first half of the height is less than that for second half
    C
    the time taken to travel first half of the height is equal to that for second half
    D
    any one of the above three situations may be correct depending upon the value of height.
