I'm confused. How do I use the Law of Conservation of Momentum if I don't have the time (how long they drove before the crashed, and the time it took for them to stop)? :S

Homework Statement I need to find the instantaneous velocity directly before a car collides with another at an intersection. It travels 24 metres with an acceleration of -5.39 m s2. The only time factor given is the light sequence: Green for 45 seconds, amber for 3 seconds and red for 5...

That makes a lot of sense. We were also given reaction times, if I recall correctly. Thank you so much, you're a life saver. ^^'

Homework Statement Two cars collide and go off in different directions. Car 1: Mass = 1010kg Distance before collision = 24m Distance after collision = 11.5m Angle from normal = 55.5° - Car 1 was stationery immediately before impact. Car 2: Mass = 1230kg Distance before collision = 22m...
