A0.20-kg stone is held 1.3 m above the top edge of a water well and then dropped into it. the well has a depth of 5.0 m. relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stoneāearth system (a) before the stone is released and (b) when it reaches the bottom of the well? (c) what is the change in gravitational potential energy of the system from release to reaching the bottom of the well?

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.)
