Answer:

D). 2.4 x10^{4} \frac{kg*m}{s}

Step-by-step explanation:

Mary is driving toward north so the angle is 90° and Danny is driving toward the east so angle is 0°

Momentum Dary= 900 kg* 22 \frac{m}{s}

Momentum Danny= 900 kg* 15 \frac{m}{s}

So the total momentum is the magnitude:

Mag= \sqrt{(900 kg*22\frac{m}{s} )^{2}+(900kg*15\frac{m}{ys} )^{2}}

mag= \sqrt{574290000}=23.96434852 x10^{3}≅2.4 x10^{4}

gavmur [86]
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 
                                                              y^2-3y=0
                                                             y(y-3)=0
                                                               y1=0 -----------y2=3
