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
stick together. After the collision, the wreckage (car and truck)
moves off in a direction of 44.0° above the x-axis.
Determine the initial speed of the truck and the final speed of
the wreckage in meters...

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...
