Question

A number of bullets fired in all possible directions with the same initial velocity ‘u’. The maximum area of ground covered by bullets is

Answer 1

Maximum radius will be when bullets are fired at angle of 45° to get maximum range.

Maximum range = maximum radius = u^2 * sin(2*theta)/g = u^2 /g

So maximum area = pi*r*r = pi*u^4 /g^2
