A box of mass Mbox is sitting on the ground with the static friction coefficient . A steady water jet from a large pressurized pipe is hitting the box horizontally. Find V1 at which the box just starts to move. What is V0 in the pipe? What is the force required to hold the pipe stationary in horizontal direction if the diameter of the pipe was D0? Neglect friction in the water flow. P0, V0 V1, D1, P1=Patm =0.5, Mbox=10 kg , Mbox
