## Homework Statement

A 50g block is attached to a vertical spring whose stiffness constant is 9N/m. The block is released at the position where the spring is unextended. What is the maximum extension of the spring? How long does it take the block to reach the lowest point?

## Homework Equations

Fsp=-kx

T=2pi(sqrtm/k)

KE=1/2mv^2

Usp = mgh

## The Attempt at a Solution

I found the time it took to reach the lowest point but cannot seem to find the first portion of the question

Here is what I did for the time it took to reach the lowest point

T=2pi(sqrtm/k)

=2pi(sqrt0.05/9)

=0.468s/2

=0.23s
