A bullet with mass m = 0,004 kg is
fired into a block of wood with mass M =
0,200 kg at rest on a horizontal surface. After impact, the block
with embedded bullet slides a
distance x = 8,00 m before coming to
rest. If the impulse exerted by friction on the block with bullet
is 1,62 N.s, what was the speed of the
bullet before impact?
