Hi,

I cannot solve this problem, I am pretty sure I used the right formula to solve it.

You have a light spring which obeys Hooke's law. This spring stretches 3.12 cm vertically when a 2.10 kg object is suspended from it. Determine the following. (a) the force constant of the spring [in me} ?9?.019230T69 X What force causes the spring to stretch? What force does the spring exert on the hanging object? Can you write a relationship between these two forces? Ny'm {b} the distance (in cm) the spring stretches if you replace the 2.1-3 kg object with a 1.05 kg object 0012133333333 x What two forces are acting on the object when it reaches equilibrium? How are these forces related? Can you use the relationship between these two forces to find aI information? cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.30 cm from its unstretched position 21453327010 38 x How does the work clone by the external agent compare to the work done by the spring and to the change in potential energy of the spring?
