## Question:

A bullet of weight ${ W }_{ 1 }$ traveling at speed ${ v }_{ 1 }$ strikes the wooden block of weight ${ W }_{ 2 }$ and exits the other side at speed ${ v }_{ 2 }$ as shown. Determine the speed of the block just after the bullet exits the block, and also determine how far the block slides before it stops. The coefficient of kinetic friction between the block and the surface is ${ μ }_{ k }$. Given: ${ W }_{ 1 }$ = 0.03 lb , a = 3 ft , b = 4 ft , ${ W }_{ 2 }$ = 10 lb , c = 5 ft , ${ v }_{ 1 }$ = 1300 ft/s , d = 12 ft , ${ v }_{ 2 }$= 50 ft/s , ${ μ }_{ k }$ = 0.5
