Bullet of mass embeds itself in a
wooden block with mass which then compresses a spring by a distance
before coming to rest. the coefficient of kinetic friction
between the block and table is (a) what is the
initial velocity (assumed horizontal) of the bullet? (b) what
fraction of the bullet’s initial kinetic energy is dissipated
(in damage to the wooden block, rising temperature, etc.)
in the collision between the bullet and the block?
the distance is (3.3m + 5.7m) = 9 meters
the displacement = (3.3m south) + (5.7m north) = 2.4 meters north
im thinking d. it is 100 times larger
