If 2 vehicles are moving toward each other from opposite directions & are the same mass & velocity then momentum=0 correct? Because p=M1V1 - M1V1

Thanks!! :)

yes

Thank You!!! :)

No, that's not correct. The formula you mentioned, p = M1V1 - M2V2, is the formula for calculating the net momentum when two objects collide and their masses and velocities are different. In this scenario, the net momentum of the system is not zero.

When two objects are moving toward each other from opposite directions with the same mass and velocity, the momentum of each object will be equal in magnitude but opposite in direction. Let's say the mass of each object is "m" and their velocity is "v". The momentum of the first object can be calculated as p1 = m * v, and the momentum of the second object can be calculated as p2 = -m * v (since the direction is opposite).

To find the net momentum of the system, you simply add the individual momenta of the two objects. So, p = p1 + p2 = m * v + (-m * v) = 0.

Therefore, in this specific scenario, the total momentum of the system is indeed zero. The objects' momenta cancel each other out because they have equal but opposite values, resulting in a net momentum of zero.
