A 7.80 gram bullet moving at 460 m/s penetrates a tree trunk to a depth of 4.4 centimeter.

(1) Use work and energy considerations to compute the average frictional force that stops the bullet.

N

(2) Suppose the friction force is constant, compute how much time elapses between the moment the bullet enters the tree and the moment it stops moving.
