Answers:
a) Momentum for Car 1: East
Momentum for Car 2: West
b) Car 2 has the greater momentum
Explanation:
a) The linear momentum is given by the following equation:
(1)
Where is the mass of the object and
its velocity.
In this case both cars have a mass of but different velocities (
east for car 1 and
west for car 2).
For Car 1:
(2)
(3)
(4)
For Car 2:
(5)
(6)
(7)
b) Having the result of the lineal momentum for both cars, we know Car 2 has the larger momentum, this can be known because Car 2 has a greater velocity.
So, if momentum is directly proportional to the mass and the velocity of the object, both objects have the same mass but different velocities; the object with greater mass will have the greater momentum.
