The TOTAL momentum (of toy truck + toy car) will be the same, before and after the collision.
The sum of the momentum of the two toys before the collision will be the same as the momentum of the two toys after the collision except for some losses due to heat dissipation and frictional losses.

yes the momentum of it is the same because P initial = P final ALWAYS!
Total momentum
This is a conservation of momentum problem. Total momentum after collision = total momentum before collision. truck momentum before is MV = 500 x 30 = 1500 kg m/s car momentum before is = 0 (car at rest) truck momentum after = MU = 500 x U Car momentum after = mU = 300 x U SO: 500U + 300U = 1500 + 0 800U = 1500 U = 1.875 m/s
Collisions in the normal setting of life on Earth are complicated. Moving objects lose energy to air friction. Momentum in many cases is transferred to the Earth, where it becomes invisible, because it is such a tiny fraction of the Earth's total momentum. A toy truck and a toy car could collide in such a way that they both stop moving, but that does not mean that momentum has disappeared; it means that since they were moving in opposite directions in the first place, the algebraic sum of their momentum was zero in the first place. In outer space, you could see a simpler example of how momentum is transferred from one moving object to another, and how it is conserved. Momentum is always conserved, but often in such a complicated way that it is not easily perceived.
Momentum defined as p=mv.. The momentum of the truck depends on its velocity
The smaller vehicle will encounter the larger velocity change.
The principle that might apply here is momentum. Momentum is mass times velocity. What should be pointed out is that velocity is speed that has a direction vector. (If the car is moving ahead in a straight line it is traveling at "x" miles per hour "forward".) The car is moving forward and comes into contact with the truck. That seems to be where the question is looking. The mass of the car times its velocity is its momentum, and this represents the energy that it is carrying into the collision. This energy will have end up being distributed among the various parts and components of the car and the truck that are compressed, deformed and/or broken by the collision. The amount of damage will be proportional to the momentum. The more the momentum (the more the "forward" energy) of the car, the more compression, deformation and breakage there will be. Was everyone wearing seat belts? Are you in good hands?
The truck is heavier
