(a).       When a 0.80 kg crown is submerged in water, its apparent weight is measured to be 7.30 N. what is the density of the crown (take density of water to be             1,000kg/m3).                                                                                                            (2.5 points)                                                                (b).         The blood flow speed through an aorta with area 3.14 x 10-4 m2 is 0.265 m/s. If hardening of the arteries causes the aorta to be constricted to an area of               2.01 x 10-4 m2, what is the flow speed in the constricted area?                           (1.5 points)

The patient was started on Milrinone continuous IV infusion in the ICU for acute management of heart failure. The nurse is reviewing the adverse effects of the drug and knows to monitor the patient for which of the following?

(a).       Three forces, F1 = 150 N, F2 = 10.0 N and F3 = 30.0 N act on a 15 kg object. If F1 and F2 act in same direction, while F3 acts in the opposite direction, what is the              magnitude of the acceleration of the object?                                                                                          (2.5 points)      b).      To negotiate a curve of radius 38 m, the maximum force of static friction (centripetal force) that can act on a 1,350-kg car going around the curve is 8,200 N.            What speed limit should be posted for the curve so that cars can negotiate safely?                                                                                                       (3.0 points)                                                                                                                        c).         With what speed must a 75 kg object be going to have a linear momentum of 925 kg m/s?             (1.5 points)
