A patient is receiving heparin per continuous intravenous infusion at 16. 5 ml/hr. The patient's aptt is 124. The patient weighs 51. 8 kg. Per the weight-based heparin therapy protocol, the heparin infusion rate is to be decreased by 2 units/kg/hr. Heparin for intravenous infusion is available as 25,000 units in 250 ml of 0. 45% sodium chloride (1/2 ns). What would the heparin infusion rate (ml/hr) be after the adjustment of 2 units/kg/hr? (round answer to the nearest tenth. ).

there is none because earth is stationary and flat.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
