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.

Part (a) Write an expression for the velocity of the
system after the collision, in terms of the variables given in the
problem statement and the unit vectors i and
j.

A car with mass MC = 1.26 x 103 kg runs into the back of a truck with mass MT = 3.23 x 103 kg that is initially at rest. Immediately after the collision, the car is moving with a speed of 1.09 m/s and the truck is moving with a speed of 3.29 m/s, both in the direction the car was initially traveling. What is the total kinetic energy lost in the collision? (Of course, the change in energy...
