Question

In the figure below, we must apply a force of magnitude 83 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 +4.6 J of work on the spring-block system; the block is then again stationary. What is the block's position (x)? (There are two answers.)
1  cm (smaller value)
2  cm (larger value)

Explanation / Answer

k = F/x = 83/.02 = 4150 N/m
