A Mack truck and , a Volkswagen, traveling at the same speed have a head- on collision. The vehicle to undergo the greatest change in velocity will be the Volkswagen, why?|||the easiest way to answer is that the mack truck weighs nearly 10 times more then the volkswagen. to put it simple regardless of either vehicles speed the mack truck has greater inertial force and will continue in it's path of motion while the volkswagen will completely stop forward motion and then continue in the path of the mack trucks inertia.
hope that helps|||This is an example of conservation of momentum.
M1*V1 = M2*V2 where M1 and M2 are the mass of the objects and V1 and V2 are the velocities of the objects.
So if M1 is larger than M2, the V2 would have to be larger than V1.
