**1. Homework Statement**

A mass of 4.5kg is dropped from a height of 3.3m above a spring. spring const is 25N/cm. How much is the spring compressed.

**2. Homework Equations**

F = 4.5*9.8 = 44.1

PE = mgh = 4.5*3.3*9.8 = 145.53

v = sqrt(2(9.8)(3.3)) = 8.04m/s

**3. The Attempt at a Solution**

The above are the few things I was able to grab out of the given information. The issue I'm having is plugging this into an equation to find the spring
