Question

What is the change in momentum of a car weighing 1500 Kg when its speed increases from 36Km/h to 72Km/h?

Answer 1

momentum before the before the velocity increases.
mass into velocity
mass=1500*velocity=36
the momentum is equal to
=54000

after the change of velocity
the mas is same
mass=1500*velocity=72
the momentum is equal to
=108000


now the change in momentum is equal to
m2-m1
108000-54000
the answer to your question is
= 54000
