Can you also explain why, for these two equations from #3, there is only one "mv" on the left side? Like just 1360v or 6970v on the left? I know I ended up with the right answers but I was confused while doing it. I used mv+mv=mv+mv. I think I just assumed the initial velocity for the other...

So since the driver made a full stop, he had to accelerate for 0m/s to 13.45 m. The truck driver claimed to be braking in anticipation of the collision meaning his acceleration has to be negative. According to my calculations, the truck's velocity before the collision was 7.09 and 5.09 after...

13.45 for car. I'm confused as to how to figure out who was at fault using this information and the information in #4 of the problem.

So for #3: 1360v=1360(13.88sin40)+6970(5.09sin10) v=93.63 m/s for the car 6970v=1360(13.88cos40)+6970(5.09cos10) v=7.08 m/s for the truck Is this correct?
