If two identical cars are traveling at different velocities, which car has the greatest momentum

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.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
