# In a ballistics test, a bullet moving horizontally with a speed of \( 500 \) \( \text{m/s} \) strikes a sandbag and penetrates a distance of \( 10.0 \) \( \text{cm} \).

In a ballistics test, a bullet moving horizontally with a speed of \( 500 \) \( \text{m/s} \) strikes a sandbag and penetrates a distance of \( 10.0 \) \( \text{cm} \).

**Part a)** Determine the magnitude of the average acceleration of the bullet while it travels through the sandbag. *(3 points)*

**Part b)** Calculate the time, in milliseconds, required for the bullet to come to rest after entering the sandbag. *(3 points)*
