Answer:
m= 2[kg]
Explanation:
Linear momentum can be calculated as the product of mass by Velocity.
where:
P = linear momentum = 3 [kg*m/s]
v = velocity = 1.5 [m/s]
m = mass [kg]

Answer:
The one with highest velocity
Explanation:
The momentum of an object is given by
where
m is the mass of the car
v is the velocity of the car
In this problem, we have two identical cars: identical means they have same mass, so
The momentum of car 1 is
while the momentum of car 2 is
By comparing the two expressions, we see that the car with greatest momentum is the one with highest velocity, since the mass is the same.
