Its about 6ft. below it and my smoke detector has gone off a couple of times for no apparent reason
Horizontal force on the wall, Fh rate of change of horiz. momentum of water jet (Newton 2) Initial horiz. vel, Vh (45.50 s 25) m/s Net change in Vh accounting for velocity reversal on impact .. ?Vh 2 (45.50 s 25) m/s .. .. ?Vh 82.47 m/s ? Net force (Fh) Rate of change in horiz. mom .. .. (in kg.m/s per s) Fh (m.?Vh / t) (m/t). ?Vh .. .. (m/t 16.90kg/s) Fh 16.90kg/s x 82.47m/s .. .. ?Fh 1393.70 N [ As the vertical velocity is unchanged, no vertical momentum is transferred to the call .. so Fv 0 ..and Fh is the net force on the wall ]
You can! look at the lid, and the base where the lid goes down. You will see that there is a thing that sticks out of the lid and goes into a hole on the base. Its that hole when pressed down starts the washer. Therefore simply press it down with something.
