    For an observer on trolley direction of projection of particle is shown in the figure, while for observer on ground ball rise vertically. The maximum height reached by ball from trolley is            

    A) 10 m    

    B)        15 m

    C) 20 m    

    D)        5 m

    Correct Answer: B

    Solution :

    [b] \[10-\text{v}\cos 60{}^\circ =0\Rightarrow \text{v}\,\text{=}\,\,\text{20 m/s}\] \[\text{H}=\frac{{{\text{v}}^{\text{2}}}\text{s}i{{n}^{2}}60{}^\circ }{2\text{g}}=15\text{ m}\]
