Obtain what the average frictional force that stops bullet

Reference no: EM13665442

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

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

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