A 20 gram bullet, traveling horizontally with a velocity of magnitude 350 m/s, is fired into a wooden block with a mass of 0.75, initially at rest on a level surface. The bullet passes through the block and emerges with its speed reduced to 150 m/s. What is the kinetic energy of the block (in J) at the instant after the bullet passes through it
