The most massive piece of equipment ever carried by a plane was a 1.24 × 105 kg generator built in Germany in 1993. How far above the ground was the generator when the potential energy associated with it was 9.17 × 108 J?

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.)
