A ball is projected from a point \( A \) with some velocity at an angle \( 30^{\circ} \) with the horizontal as shown in the figure. Consider a target at point \( B \). The ball will hit the target if it is thrown with a velocity \( v_{0} \) equal to
(1) \( 5 \mathrm{~m} \mathrm{~s}^{-1} \)
(2) \( 6 \mathrm{~m} \mathrm{~s}^{-1} \)
(3) \( 7 \mathrm{~m} \mathrm{~s}^{-1} \)
(4) None of these
