A 60 kg post-op patient is receiving mechanical ventilation in the ICU. ABG results and related data are:Mode: SIMV-VC                                   FiO2:    50                 PS:   5 cmH2O Mandatory Rate: 10 bpm                       Vt:  500 mL Total Rate:  10 bpm                               Insp Flow:  50 Lpm                   ABG:  pH 7.31/ PaCO2 61/ PaO2 88/ HCO3 26 Which of these ventilator adjustments would correct the PaCO2 in this patient?

Two forces act on a 16-kg object. The first force has a magnitude of 68 N and is directed 24° north of east. The second force is 32 N, 48° north of west. What is the acceleration of the object resulting from the application of these two forces to the object?
