Question

Calculate the impulse imparted when a 3,000-kg car hits a wall at 60. m/s and comes to a stop.

Answer 1

Now If I'm not totally wrong impulse should be the same as the change in momentum and when the car come to a stop the momentum most equal 0, so we should be able to calculate it using the equation of momentum:
\[J=\Delta p=p_{before}-p _{after}\]
Where:
\[p=mv\]
