01. Car 1 was sitting at rest when it was hit from the rear by car 2 of identical mass. Both
cars had their breaks on and they skidded together 6 m in the original direction of motion.
If the stopping force is ~ 0.7  (combined weight of the cars) , i. e.,  = 0.7, find the
approximate speed of car 2 just before the collision took place. [18.14 m/s

Which object is most likely represented by a dot?

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
