If a spring has a constant of #6 (kg)/s^2#, how much work will it take to extend the spring by #50 cm #?
The given potential energy of a spring can be found by the equation
Extension from previous point is
Since we have not been provided with initial extension of the spring, we'll assume that the spring was at equilibrium initially with no potential energy. So the total potential energy of the spring will be the potential energy of spring due to this
So this will be the amount of work one has to do to stretch the spring by
