3. A bullet with a mass of 3.6 grams is moving horizontally with a velocity v and strikes a 5-kg block of wood, becoming embedded in it. After the impact the block and bullet are sliding together with a velocity of 0.5 m/s. a. What is the velocity, v, of the bullet before it strikes the block? b. If the duration of the impact is 0.05 s, what is the average force exerted on the block by the bullet?
