A 4.25 g bullet traveling horizontally with a velocity of magnitude 375 m/s is fired
into a wooden block with mass 1.12 kg, initially at rest on a level frictionless surface.
The bullet passes through the block and emerges with its speed reduced to 122 m/s.
How fast is the block moving just after the bullet emerges from it

dP1 = dP2
.00425*(375 - 122) = 1.12*Vb
Vb = 0.96 m/s
.00425*(375 - 122) = 1.12*Vb
Vb = 0.96 m/s
