The figure below shows a force versus position graph for a spring/block system. If Fs=160N and the block is released at x = 12 cm (not shown on figure) how much work is done on the block by the spring as the block goes from x = + 8.0 cm to x = + 5.0 cm. HInt: Determine k from the graph. Don't forget to convert from cm.

A block attached to a 15 N/m-spring constant spring moves on a frictionless horizontal surface, its position-vs-time graph is shown below. What is the total mechanical energy of the block-spring system, in Joules? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit x (cm) 20 is needed in your answer, it is already given in the question statement. 0 -20- ਲਈ 4 6 8 –t (s)
