Question

You and your friend are honing your marksmanship skills by shooting bullets into blocks. You decide to fire the bullet into a steel block from which the bullet will bounce off elastically with the same speed at which it hit the block. Your friend decides to use the same gun from the same distance, but fire the bullet into a wooden block of mass equal to the steel block, such that the bullet will get embedded in the wooden block. Knowing that you are taking physics, your friend asks “I wonder which block will take off faster after the collision?” What is your answer? Explain your reasoning.

HINT: When you explain your reasoning you need to describe your answer clearly and completely by providing all reasons that support your answer.
