A0.200-kg mass attached to the end of a spring causes it to stretch 5.0 cm. if another 0.200-kg mass is added to the spring, the potential energy of the spring will be (show work, of explain your answer) a) twice as much. b) the same. c) 4 times as much. d) one-half as much. e) 3 times as much. pushing on the pump of a soap dispenser compresses a small spring. when the spring is compassed 0.50 cm, its potential energy is 0.0025 j. what is the spring constant of the spring? (show work) a diver who weighs 500 n steps off a diving board that is 10 m above the water. the diver hits the water with kinetic energy of a) 5000 j. b) 510 j. c) 500 j. d) 10 j. e) more than 5000 j. a 40.0-kg suitcase is being pulled along long an inclined ramp at an airport, by means of a strap which exerts a force of 10.0 n at an angle of 47.0 degree above the horizontal. if the ramp makes an angle of 15 degree above the horizontal. how much work is done by this force on the suitcade when it move 10.0 m along the ramp? how work or explain your answer.
a) 84.8 j
b) 68.2 j
c) 100 j
d) 96.6 j
e) 46.6 j
