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.

(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.
