Question

A 15 g bullet is fired at 610 m/s into a 4 kg wood block that is at rest on the edge of 75 cm high table. The bullet embeds itself in the block and carries it off the table.

a. What are forces acting on the block+bullet? (Or draw a free body diagram of forces acting on the block+bullet.)

b. What was the momentum of the bullet before it hit the block?

c. Write down the statement of conservation of momentum specifically for this case.

d. At what speed does the block+bullet starts to fall?

e. How far from the point directly below the table’s edge does the block land? (Assume that the block does not move once it touches the land.)
