Please show work and box answer. thank you
1. A spring with an unstretched length of 50 mm expands from a length of 20 mm to a length of 40 mm. If the stiffness of the spring is 5 kN/m, the work done on the spring is? 5 points
2. If a spring force is F = 5 s2 N/m and the spring is compressed by s = 0.7 m, the work done on a particle attached to the spring is? 5 points
