Firefighters are on the scene of a working fire and using an 1 1/8" straight bore nozzle to penetrate the ceiling. As the straight steam hits the ceiling it breaks the drywall, in small pieces, accelerates n the direction of the stream. Which equation would represent this?

a=F/m

F = gm

F=GM1M2/r12 2

Vav=Vr/2=d/(t-to)
