# A 30 gram bullet is fired with a speed of 500 meters per second into a wall. 

A \(30 \, \text{g}\) bullet is fired with a speed of \(500 \, \text{m/s}\) into a wall.

**Part a)** If the acceleration of the bullet is constant and it penetrates \(12 \, \text{cm}\) into the wall, calculate the force on the bullet while it is stopping. *(3 points)*

**Part b)** If the deceleration of the bullet is constant and it penetrates \(12 \, \text{cm}\) into the wall, how much time is required for the bullet to stop? *(3 points)*
