Please help this urgent problem!~ 1. The problem statement, all variables and given/known data An elastic spring is made of two springs connected one after the other. The coefficients of the springs are k 1 = 1,476 N/m and k 2 = 3,271 N/m. Calculate the work necessary to strech the spring for x=10cm. 2. Relevant equations E=0.5 * k * x^^2 k= spring constant x= distance 3. The attempt at a solution correct solution is 5.09 <-- this is from professor's note but I still find how this value became.. please help me out.
