E75605 ¢ radls As an aid In working this problem, consult Concept Simulation 10.3. A block of mass m m 0.760 kg ls fastened to an unstrained horizontal spring whose spring constant Is k n 72.0 Nlm. The block ls given a displacement of +0.12!) m, where the + sign indicates
that the displacement is along the +x axis, and then released From rest. (a) What Is the force (magnitude and direction) that the spring exers on the block just before the block is released?
