    If a projectile is launched with velocity \[{{v}_{0}},\] making an angle \[\theta \] with x-axis, then its time of flight T is

    A)  \[T=\frac{v_{0}^{2}\sin 2\theta }{g}\]

    B)  \[T=\frac{v_{0}^{2}\,\,{{\sin }^{2}}\theta }{2g}\]

    C)  \[T=\frac{v_{0}^{2}}{g}\]

    D)  \[T=\frac{2{{v}_{0}}\,\sin \,\theta }{g}\]

    Correct Answer: D

    Solution :

    Time of flight, \[T=\frac{2{{v}_{0}}\,\sin \theta }{g}\]
