    Figures shows four paths for a kicked football ignoring the effects of air on the flight rank the paths according to the 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 :

    \[R=\frac{{{u}^{2}}\,\sin \,2\,\theta }{g}=\frac{2(u\,sin\,\theta \,)(u\,cos\,\theta )}{g}\,\,=\,\,\frac{2\,{{u}_{x}}{{u}_{y}}}{g}\] \[\therefore \] Range \[\propto \] horizontal initial velocity component \[{{u}_{x}}\]. In path range 4 is maximum, so football has maximum horizontal velocity component in this path.
