1. The problem statement, all variables and given/known data A 7500kg truck traveling at 5 m/s east collides with a 1500kg car moving at 20 m/s direction south of west. After the collision, the two vehicles remain tangled together. A) With what speed and direction does the entangled wreckage move immediately after the collision? B) If the coefficient of friction between the sliding wreckage and the road is .85, how far will the wreckage go before it slides to a stop? 2. Relevant equations 3. The attempt at a solution A) (7500kg)*(5m/s) + (1500kg)*(20m/s) = )7500kg+1500kg)V V= 7.5 m/s is that right?
