Hope can sometimes be disappointing

oh damn it.. Sorry, I guess I read it wrong.. I thought the person was firing the gun.. 3.645 seconds

I also got 14.72N..

The conservation of energy/mass is the exact same law!! All the other laws are similar in that they involve that some quantity cannot be created or destroyed..

wow, good job. They are vectors, though.. the torque is 72Nm in the k direction, and the angular momentum is 72t Js in the k direction.
nice, your turn to post a question.

um.. It's really not that hard. Involves some knowledge of angular momentum.. and calculus

The answer, of course, is 14.08 m/s in the opposite direction of the first car.
