and what is the question?
You cannot use conservation of energy here, only conservation of momentum.
Hi, i really need help with this question.
Two identical cars hit each other and lock bumpers. A car moving with a speed of 90 km/h approaches a stationary car

The question is: two identical cars hit each other and lock bumpers. If a car moving with a speed of 90km/h appraoches a stationary car, what is the speed immediately after coupling cars.
M1V1+M2V2=(M1+M2)V
solve for V
solve for V
Thank you that was bothering me for so long.
In the problem, the mass isn't known though, you know that the one car is identical to the other though. i end up getting,
90km/h=M1*V
What do I do after that?
90km/h=M1*V
What do I do after that?
