    Figure shows four paths for a kicked football. Ignoring the effects of air on the flight, rank the paths according to initial horizontal velocity component, highest first

    A)  1, 2, 3, 4                              

    B)  2, 3, 4,1

    C)  3, 4, 1, 2                              

    D)  4, 3, 2, 1

    Correct Answer: D

    Solution :

    Horizontal    distance    (range) = horizontal; component of velocity \[\times \] time period \[\therefore \]Horizontal range \[\alpha \] horizontal component of velocity. Horizontal range                 \[{{R}_{4}}>{{R}_{3}}>{{R}_{2}}>{{R}_{1}}\] Therefore, horizontal velocity component,                 \[{{({{v}_{H}})}_{4}}>{{({{v}_{H}})}_{3}}>{{({{v}_{H}})}_{2}}>{{({{v}_{H}})}_{1}}\]
