A 454 kg CAR approaches a stop light moving 20 m/s, but the driver is texting and does not slow down! The CAR collides with a TRUCK (908 kg) at rest at the stop light. After the collision the CAR is traveling at 5 m/s and the TRUCK is traveling at 7.5 m/s in the same direction. What is the total (sum) momentum of the CAR & TRUCK Before the collision? and After? Can somebody pleeease walk me through this? With equations and your thought process and stuff. Thank you *will give brainliest*
