Estimate the decrease in kinetic energy of the bullet

Reference no: EM13505721

A 6.00 g bullet, traveling horizontally with a velocity of magnitude 450m/s, is fired into a wooden block with mass of 0.780kg, initially at rest on a level surface. The bullet passes through the block and emerges with its speed reduced to 170m/s. The block slides a distance of 44.0cm 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?
