15-135. A power lawn mower hovers very close over theground. This is done by drawing air in at a speed of 6 m/sthrough an intake unit A, which has a cross-sectional area ofAA = 0.25 m², and then discharging it at the ground, B,where the cross-sectional area is Ag = 0.35 m². If air at A issubjected only to atmospheric pressure, determine the airpressure which the lawn mower exerts on the ground whenthe weight of the mower is freely supported and no load isplaced on the handle. The mower has a mass of 15 kg withcenter of mass at G. Assume that air has a constant densityof p. = 1.22 kg/m³.Lall
