What is the kinetic energy of a 6.00 kg toy car that is going at 1.75 m/s across the floor?

Asimply means that over time there was some sort of change.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

Which sections of the heating curve illustrate this process?
