Mary is driving a car of mass 900 kilograms toward the north with a velocity of 22 meters/second. Danny is driving his 900-kilogram car with a velocity of 15 meters/second toward the east. They collide and both cars move together afterwards. What is the magnitude of the resultant momentum of the cars after the collision?
They are at 90 degrees to each other.
resulatant=sqrt(danny^2 + mary^2)
