SUMMARY
The discussion centers on calculating the change in kinetic energy for a 1609 kg car traveling at 11.9 m/s that comes to a complete stop after hitting a tree. The initial kinetic energy (KE) is calculated using the formula KE = 1/2 mv², resulting in 113925.245 J. Since the car comes to rest after the impact, the final kinetic energy is 0 J. Therefore, the change in kinetic energy is 113925.245 J.
