A block of weight = 25.0 N sits on a frictionless inclined plane, which makes an angle = 34.0 with respect to the horizontal, as shown in the figure. A force of magnitude F= 14.0 N, applied parallel to the incline, is just sufficient to pull the block up the plane at constant ...

we must apply a force of magnitude 82.0 N to hold the block stationary at x=-2.0 cm. From that position, we then slowly move the block so that our force does +8.0 J of work on the spring–block system; the block is then again stationary. What are the block's positions, in cm...
