The two cars have same momentum
Explanation:
The momentum of an object is given by the equation
[tex]p=mv[/tex]
where
m is the mass of the object
v is its velocity
For the car A in this problem,
m = 5 kg
v = 10 m/s
So its momentum is
[tex]p_A = (5 kg)(10 m/s) = 50 kg m/s[/tex]
For car B we have,
m = 10 kg
v = 5 m/s
So its momentum is
[tex]p_B = (10 kg)(5 m/s)=50 kg m/s[/tex]
Therefore, the two cars have same momentum.
