To find the magnitude of the total momentum between the two cars after the collision, we need to add up their momenta.
The car going north had a momentum of 10 kg●m/s, while the opposing car had a momentum of 25 kg●m/s. Since momentum is a vector quantity, we need to consider their directions as well. The momentum of the car going north is positive because it is in the north direction, while the momentum of the opposing car is negative because it is in the opposite direction.
So, the total momentum between the two cars after the collision is:
Total momentum = 10 kg●m/s + (-25 kg●m/s)
Total momentum = -15 kg●m/s
The magnitude of the total momentum is the absolute value of the total momentum:
Magnitude of total momentum = | -15 kg●m/s |
Magnitude of total momentum = 15 kg●m/s
Therefore, the magnitude of the total momentum between the two cars afterwards is 15 kg●m/s.
Answer: b. 15 kg●m/s
4. A car is traveling north and has a collision with another car going in the opposite direction. The car going north had a momentum of 10 kg●m/s before the collision, while the opposing car had a momentum of 25 kg●m/s. The magnitude of the total momentum between the two cars afterwards will be: a. 5 kg●m/s b. 15 kg●m/s c. 250 kg●m/s d. 10 kg●m/s
