Congratulations- you've finished your degree and now you're employed by the police department, solving (low stakes) crimes. Today, you're looking at the aftermath of a car accident. Both drivers swear the other one ran a stop sign, and you have to figure out who is telling the truth. What is known is that one car, mass 1550 kg , was traveling north and the other car, mass 1300 kg , was traveling west when they collided. They stuck together and skidded for a distance 21.5 m , at an angle 13.2 north of west, before they came to a stop. You measure the coefficient of friction between the tires and the pavement as 0. 110. Part A v Part B v Part C v Part D What was the speed of the car moving north right before the accident? Express your answer with appropriate units. View Available Hint(s) HA - O ( ? m v1 Value SPart E What was the speed of the car moving west right before the accident? Express your answer with appropriate units. > View Available Hint(s) O m Value S PartB If you use your physics knowledge, this is enough to solve the crime, although it won't be easy. We're going to have to work backwards- thinking first about what happened after the collision and then what happened in the collision itself Let's start by figuring out how fast the cars were going right after the collision (when they were stuck together). Express your answer with approprate units. View Available Hint(s) m 6812
