A 1.50 x 103 kg car traveling at 100 km/h South collides with a 1.20 x 103 kg car traveling North at 100 km/h. The heavier car continues to move South after
the collision, but slows to 25.0 km/h. How fast is the lighter car moving after the
collision?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
