A ball is projected from a point A with some velocity at an angle 30° with the horizontal as shown in Fig. Consider a target at point B. The ball will hit the target if it is thrown with a velocity v0 equal to 

a
5 ms-1
b
6 ms-1
c
7ms-1
d
None of these

detailed solution

Correct option is D

Applying equation of trajectory, we get0.5=32tan30°-g322v02cos230°⇒v0=∞
