which object has the least amount of kinetic energy? a spinning top, golf all on a grass covered hill in sunlight, a person filling a glass of water from the faucet to overflowing, a roller coaster train half way down the first hill of a roaller coaster track?

Which of the following is an example of motion in two dimensions?

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.)

At what time will the interfering waves have an amplitudeof zero?
