If a car is resting at stop sign
then we can say speed of car is ZERO
[tex] v = 0[/tex]
now we know that momentum is given as
[tex]P = mv[/tex]
it is product of mass and velocity
so if the car is resting at the stop sign then its velocity will be zero
here we know that
m = 1360 kg
[tex]P = 1360 * 0[/tex]
[tex]P = 0[/tex]
so the momentum of car will be ZERO
