A gun is firing bullets with velocity `v_0` by rotating it through `360^@` in the horizontal plane. The maximum area covered by the bullets is |
Answer» The maximum area will be equal to the area of the circle with radius equal to the maximum range of projectile. Maximum area, `pi r^2 = pi (R_(max))^2 = pi ((u^2)/(g^2)) = pi (u^4)/(g^2)` `[As r = R_(max) = u^2//g for theta = 45^@]`. |
