You are bowling and have one pin left standing. You roll
the 10kg bowling ball at a velocity of +1
m
s
into the 1kg pin, which is at rest. After the ball hits the pin, the pin
and the ball both travel along a straight line. If the final velocity of the ball after it hits the pin is +0.9
m
s
, what
is the kinetic energy of the pin after it is struck by the ball?
