A. k = F/d = M*g/d = 1.9*9.8/0.029 = 642N/m.
B. 0.0906m * 642N/m = 58.2N.
Mass = 58.2/9.8 = 5.94kg.
You find that if you hang a 1.90 kg weight from a vertical spring, it stretches 2.90 cm .
Part A
What is the force constant of this spring in N/m?
Part B
How much mass should you hang from the spring so it will stretch by 9.06 cm from its original, unstretched length?
