Answer to Question #201763 in Physics for manatee

Question

A 2.00 [kg] frictionless block is attached to an ideal spring of force constant 300. [N/m]. At

Answer 1

If we attach this block to the spring, the compression or extension of the spring can be found from the following equilibrium of Hooke's force and the force of gravity:

$$kx=mg,\\\space\\ x=\frac{mg}{k}=0.065\text{ m}.$$
