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 1775 kilogram car traveling to the right 1.45 m/s at collides with a 1360 kilogram car going to the left at 1.00 m/s. Measurements show that the heavier car's speed just after the collision was 0.235 m/s in its original direction. You can ignore any road friction during the collision.
(a) Find the speed of the lighter car just after the collision?
m/s
(b) Find the change in the combined kinetic energy of the two-car system during this collision.
