A 7.80 grams bullet moving at 690 m/s penetrates a tree trunk to a depth of 6.40 centimeter.
(a) Use work and energy considerations to compute the average frictional force that stops the bullet.
N
(b) Assuming the frictional force is constant, find how much time elapses between the moment the bullet enters the tree and the moment it stops moving.
