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

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=

Momentum Danny=

So the total momentum is the magnitude:

Mag=
