1. In this experiment, a 0.20 kg mass (m1) hangs vertically from a spring and an elongation of the spring of 9.50 cm (r1) is recorded. With a mass (m2) of 1.00 kg hanging on the spring, a second elongation (r2) of 12. 00 cm is recorded Calculate the spring constant k in Newtons per meter (N/In). (Note: The equilibrium position is not zero.) k: 2. If the same spring (as in part 1) causes an elongation (r3) of 18 cm when a mass (m3) is attached to it, what will be the mass in SI units? m3= 3. If the same mass (111;) causes an elongation (r4) of 5 cm when it is attached to a different spring, what will be its spring constant kin Newtons per meter (me). The equilibrium position is 1.3 cm
