A blue car with mass mc = 481 kg is moving east with a speed of vc = 23 m/s and collides with a purple truck with mass mt = 1289 kg that is moving south with a speed of vt = 10 m/s . The two collide and lock together after the collision.
*What is the magnitude of the initial momentum of the car?
*What is the magnitude of the initial momentum of the truck?
*What is the magnitude of the momentum of the car-truck combination immediately after the collision?
Compare the initial and final kinetic energy of the total system before and after the collision:
_ *KEi = KEf
_ *KEi > KEf
_ *KEi < KEf

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s
and a 1500 kg pickup is traveling north toward the same
intersection. The car and truck collide at the intersection and

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.

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...
