Answer:
B. The force would be the same in both cases.
Explanation:
According to Newton's 3rd law where impulse was equated to the momentum formula.
F × t = M × V
where,
Force = F
V = velocity
Since, Impulse is force multiplied by time, whereas the time of contact is the same for both, therefore the impulse is the same in magnitude for the two trucks.
Case 1: Hitting the other car
Case 2: Hitting the brick wall
In Case 1, both the cars are identical and have same velocity whereas in the Case 2, the wall is stationary.
The case of hitting the brick wall have the same impact force as hitting the other car, because they have the same change in momentum.
Therefore, The force would be the same in both cases.
