Please answer parts A,B andC using the data given in the question.
Mallings View Tell me AaBbCcDdEe Caption Heading 1 3.) The following graph shows how a variable force, in this case a spring force, acts over a distance: F F = kx x = x0 x = Xf a.) What value of stretch (x) has the force least? Which has the greatest? b.) Show that the shaded area under the force curve is just the potential energy stored in the spring by the force AU = kx} - kx; %3D (Hint: What is the area of a triangle?) c.) What units does the "length" of the triangle have? What units does the "height" of the triangle have? What units does the area under the curve have? (You will use this result in Part II of the lab.)
