Question

a gun is firing bullets with velocity 'u' by rotating through 360 degree in the horizontal plane .
the maximum area covered by the bullets is?

Answer 1

each bullet is fired with intial velocity u
the distance covered by the bullet is considered as  radius r
the maximum range is $r= \frac{ u^{2} }{g}$
therefore maximum area is given
by $A= \pi r^{2}= \pi \frac{ u^{4} }{ g^{2} }$
g-acceleration due to gravity

Answer 2

Answer:

Hence this is the required answer.
