A second cannon $($B$)$ fires a bullet vertically also with a speed v$0$ with the intention of intercepting the bullet from cannon A and preventing it from reaching its destination. Calculate: How long after cannon A has fired must cannon B fire to ensure that the two bullets intercept each other. The distance between the two cannons is known to be L$=$D$/2.$ Option A: $0\mathrm{.}073$ s Option B: $0\mathrm{.}219$ s Option C: $0\mathrm{.}146$ s Option D: $0\mathrm{.}292$ s
