A large number of bullets are fired in all directions with same speed

1.	A large number of bullets are fired in all directions with same speed u. The maximum area on the ground covered by these bullets will be
Answer» Given :- Speed of bullets = u m/s As we know that bullets will move in Projectile. Area covered = πr² For MAXIMUM Area, r = R(MAX) = u²/g (When Ø = 45° then R is max). Maximum Area = πr² M. A. = π (u²/g)² M.A. = πu⁴/g² Hence, Maximum Area covered = πu⁴/g².

Answer»

Given :-

Speed of bullets = u m/s

As we know that bullets will move in Projectile.

Area covered = πr²

For MAXIMUM Area,

r = R(MAX) = u²/g (When Ø = 45° then R is max).

Maximum Area = πr²

M. A. = π (u²/g)²

M.A. = πu⁴/g²

Hence,

Maximum Area covered = πu⁴/g².
