When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1880-kg car traveling to the right 1.64 m/s at collides with a 1445-kg car going to the left at 1.09 m/s. Measurements show that the heavier car's speed just after the collision was 0.215 m/s in its original direction. You can ignore any road friction during the collision.

What was the speed of the lighter car just after the collision?

m/s

(b) Calculate the change in the combined kinetic energy of the two-car system during this collision.
