The block in Figure 7-11a lies on a horizontal frictionless surface and is attached to the free end of the spring, with a spring constant of 40 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 2.8 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops.(adsbygoogle = window.adsbygoogle || []).push({});

Assume that the stopping point is reached.

(a) What is the position of the block?

please someone help me with this problem, its been so annoying. i figured you were to use Hooke's Law to solve it, plugging in 2.8 N for the force and 40 N/m for k. doing this gives you .07. however, the answer is not .07 because it tells me i am wrong when i put that in. does anyone know where i went wrong???
