Comin' out the nozzle on a fire hose, flyer than swatters
The Units for N is actually KG M/Sec^2 so if you have a force requirement of 1000 N that is also written as 1000 KG M/ Sec^2 If you know the hose delivers 40 KG/ Sec You need to solve for how fast that 40 KG/sec must be moving in order to knock the door down. So(Cancel units below.) 1000 KG M ~~~ Sec ~~~~~ 1000 M (KG and Sec cancel) - X -- Sec*Sec ~~~~ 40 KG ~~~~~ 40 Sec (KG and Sec cancel ) You are left with 25 Meters / Sec
