## Homework Statement

1.) A 0.22 rifle bullet, traveling at 350 m/s, strikes a block of soft wood, which it penetrates to a depth of 0.130 m. The block of wood is clamped in place and doesn't move. The mass of the bullet is 1.80 g. Assume a constant retarding force. A.) How much time is required for the bullet to stop? B.) What force, in Newton's, does the wood exert on the bullet?

## Homework Equations

(I'm not sure)

V = Vo + at

V^2 = Vo^2 + 2a (X - Xo)

## The Attempt at a Solution

As of now, I have no clue because this is new to me. Help would be really appreciated. Thanks!
