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...
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...
