What is the magnitude of the force exerted by a spring with a spring constant of 447N/m, if it is stretched by 77cm?

You attach a 46.8g weight to a vertical spring and let it slowly move down until it is in equilibrium. By how much, measured in cm, the spring is stretched at equilibrium if the spring constant is 24N/m? g=9.8m/ s2

What is the period of the oscillations of a mass-spring system, measured in seconds, if the mass of the object is 3.2kg and the spring constant (or force constant) is 14.9N/m? Do not include the units in the answer.

Assume that you have plotted the period squared vs. mass of the system and the slope is 4.67. What is the spring constant or the force constant in N/m?
