1. A bullet moving at 200 m/sec strikes a tree and penetrates a distance of 0.75 cm into the tree before stopping. What was the deceleration of the bullet? How long did it take the bullet to stop? Assume constant deceleration.
A 7.80 g bullet is initially moving at 560 m/s just before it penetrates a tree trunk to a depth of 5.60 cm. (a) What is the magnitude of the average frictional force (in N) that is exerted on the bullet while it is moving through the tree trunk? Use work and energy considerations to obtain your answer. (b) Assuming the frictional force is constant, how much time (in s) elapses between the moment the bullet enters the tree trunk...

(a) A rifle fires a bullet and the bullet strikes a tree. The bullet is moving at 1250 m/s when it strikes the tree and the bullet follows a straight-line path, coming to rest 0.44 m deep in the wood of the tree. Assume the acceleration is constant as the bullet slows in the wood. Calculate the acceleration of the slowing bullet in the tree. (b) Calculate the time for the bullet to move the 0.44 m into the tree.
A 7.80-g bullet moving at 510 m/s strikes the hand of a superhero, causing the hand to move 5.90 cm in the direction of the bullet's velocity before stopping. (a) Use work and energy considerations to find the average force that stops the bullet. N (b) Assuming the force is constant, determine how much time elapses between the moment the bullet strikes the hand and the moment it stops moving. s
A 7.80-9 bullet moving at 470 m/s penetrates a tree trunk to a depth of 4.90 cm. (a) Use work and energy considerations to find the average frictional force that stops the bullet. 18728.48 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
