Determine the decrease in kinetic energy of the bullet

Reference no: EM13270599

A bullet with a mass of 4.25g , traveling horizontally with a speed of 434m/s , is fired into a wooden block with mass of 0.786kg , initially at rest on a level surface. The bullet passes through the block and emerges with its speed reduced to 116m/s . The block slides a distance of 43.7cm along the surface from its initial position.

A.) What is the coefficient of kinetic friction between block and surface?

B.) What is the decrease in kinetic energy of the bullet?

C.) What is the kinetic energy of the block at the instant after the bullet passes through it?
