A car with mass mc=1370kgmc=1370kg is traveling west through an intersection with a speed of vc=9.61m/svc=9.61m/s when a truck of mass mt=1840kgmt=1840kg traveling south at vt=9.38m/svt=9.38m/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=0.500μk=0.500. Associate the positive xx direction with east and the positive yy direction with north.
