Reference no: EM13664818

A 7.80 gram bullet moving at 540 m/s penetrates a tree trunk to a depth of 6.4 centimeter.

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

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