If a spring has a constant of #2 (kg)/s^2#, how much work will it take to extend the spring by #44 cm #? Physics Work and Energy Work 1 Answer Junaid Mirza Mar 20, 2018 #"0.1936 Joule"# Explanation: Potential energy #("U")# gained by spring on stretching is #"U" = 1/2\ "kx"^2# #"U" = 1/2 × "2 kg/s"^2 × ("0.44 m")^2 = "0.1936 Joule"# From work energy theorem, this equal to the amount of work done on the spring to stretch it by #"44 cm"# Answer link Related questions What is a force?
