A 4.00-gram bullet has a velocity of 600 meters per second when it hits a stationary 1.996-kilogram block of wood suspended by two ropes of negligible mass. The bullet imbeds itself in the block.

A) Find the velocity of the block and bullet immediately after impact.

B) What was the total kinetic energy of the block and bullet immediately after impact?

C) If all the kinetic energy was transferred to potential energy, how high did the block swing?
