(5%) Problem 16: A car with mass me = 1520 kg is traveling west through an intersection with a speed of te=11.41 m/s when a truck of mass m = 1790 kg traveling south at t = 9.23 m/s fails to yield. The vehicles collide, they stick together, and they slide on the asphalt which has a coefficient of kinetic friction of p=0.500.
