Question

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

Answer 1

Answer:

The one with highest velocity

Explanation:

The momentum of an object is given by

$p=mv$

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

$m_1 = m_2 = m$

The momentum of car 1 is

$p_1 = mv_1$

while the momentum of car 2 is

$p_2 = mv_2$

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.
