## Homework Statement

A 6.20g bullet traveling at 485m/s embeds itself in a 1.73kg wooden block at rest on a frictionless surface. The block is attached to a spring with k = 79.0N/m

A)Find the Period

B)Find the Amplitude

C)Find the totla energy of the bullet+block+spring system before the bullet enters the block.

D)Find the total energy of the bullet+block+spring system after the bullet enters the block.

## Homework Equations

T=2∏[itex]\sqrt{}k/m[/itex] or T=2∏ω

K=1/2m

^{v}

P=1/2k

^{x}

X=Acos(ωt)

Vx,max=ωA

## The Attempt at a Solution

Ok so i found the Time T=2πsqrt(1.7362/79)== .931s

Now i'm literally stumped with finding the amplitude. I've tried Vmax=ωA and a few other ways and can't understand what i'm doing incorrectly.
