A car with mass mc=1120kg is traveling west through an intersection with a speed of vc=7.41m/s when a truck of mass mt=2040kg traveling south at vt=15.43m/s fails to yield. The vehicles collide, they stick together, and they slide on the asphalt which has a coefficient of kinetic friction of μk=0.500. Associate the positive x direction with east and the positive y direction with north.
