A 7.80-g bullet moving at 640 m/s penetrates a tree trunk to a depth of 6.1 cm.

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

(b) Assuming the friction force is constant, determine how much time elapses between the moment the bullet enters the tree and the moment it stops moving.
