A block of mass 2.5kg is pressed against a spring and compresses the spring to a length of
10.0 cm. Then, the block is released and begins to move to the right as the spring returns
to its natural length of 21.4 cm. The spring has a spring constant of 88 N/m. Using Hooke's
Law, determine the force in the spring.
Pay attention to your units (specifically your values of spring length). Answer in units of
