Mathematics: Mary is driving a car of mass 900 kilograms toward the north with a velocity of 22 meters/second. danny is driving his velocity of 15 meters/second toward the east. they collide and both cars move together afterwards. what is the mag momentum of the cars after the collision? a. 1.8 x 104 kilogram-meters/second b. 2.0 x 104 kilogram-meters/second c. 2.7 x 104 kilogram-meters/second d. 2.4 x 104 kilogram-meters/second

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