## Homework Statement

An 8.00 g bullet is fired into a 160 g block that is initially at rest at the edge of a table of 1.00 m height. The bullet remains in the block, and after the impact the block lands d = 2.2 m from the bottom of the table. Determine the initial speed of the bullet.

## Homework Equations

y=voyt + 1/2 gt

^{2}

vox = x/t

mbvb = (mb + mB) v

## The Attempt at a Solution

y=voyt + 1/2 gt

^{2}

t

^{2}=-2(1m)/9.8 m/s

^{2}

t=0.45s

vox = x/t

vox = 2.2m / 0.45s

vox= 4.889 m/s

mbvb = (mb + mB) v

vb= ((0.008 kg + 0.160kg)/0.160kg) 4.889 m/s

vb=5.13 m/s
