A car with mass
mc = 1385 kg is traveling west through an
intersection at a magnitude of velocity of vc =
10.5 m/s when a truck of mass mt = 1984 kg
traveling south at vt = 12.6 m/s fails to yield
and collides with the car. The vehicles become stuck together and
slide on the asphalt, which has a coefficient of friction of
μk = 0.5.
