Answer:
The trucks must have equal masses that is they must have same load.
Explanation:
Momentum refers to the product of the mass of the object and velocity.
As momentum has both magnitude and direction, it is a vector quantity.
In the given problem, it is given that after the collision, the trucks move at more than half the original speed of the moving truck. Therefore, the trucks must have equal masses that is they must have the same load.
