Answer:
A. less
Explanation:
The momentum of an object is directly proportional to it mass and velocity. It is the product of mass and velocity of the object. Given as
[tex]Momentum (p) = Mass (m) \times Velocity (v)[/tex]
So the momentum of car,
[tex]p_{c} = m_{c}\times v_{c}[/tex]
Momentum of truck,
[tex]p_{t} = m_{t}\times v_{t}[/tex]
We know that, mass of car is less than that of truck and velocity of the two are same. It is implied that, momentum of car will be less than that of truck.
