Question: A 11-g bullet with an initial speed of 306 m/s is shot directly at a 1-kg wooden block, which rests on a frictionless surface. What is the speed of the block, after the bullet is embedded in the block?

(Although this is not justified, calculate your answer to 4 significant figures. This will uncover any conceptual errors you might make.)

A 11-g bullet with an unknown initial speed is shot directly at a 1.2-kg wooden block, which rests on a frictionless surface. After impact, the bullet is embedded into the block, and the block moves at a speed of 2.17 m/s. What was the initial speed of the bullet?

A 12-g bullet with an initial speed of 301 m/s is shot directly at a 1.1-kg wooden block, which rests on a frictionless surface. The bullet passes through the block and emerges with a speed of 270 m/s. What is the speed of the block, after the bullet has passed through the block?

A 10-g bullet with an initial speed of 301 m/s is shot directly at a 1-kg wooden block, which rests on a frictionless surface. The bullet passes through the block, after which the block is moving at a speed of 0.186 m/s. What is the speed of the bullet after it has passed through the block?

A 10-g bullet with an unknown initial speed is shot directly at a 1.2-kg wooden block, which rests on a frictionless surface. The bullet passes through the block and emerges with a speed of 295 m/s, after which the block is moving at a speed of 0.178 m/s. What was the speed of the bullet before it hit the block?
