An ant with mass 0.15 g lands on one end of a floating 4.75 g stick. After sitting at
rest for a moment, it runs toward the other end with a speed of 3.8 cm/s relative to
the river. What is the speed of the stick if it moves in the opposite direction?

momentum is conserved
.15 * 3.8 = 4.75 * v
.15 * 3.8 = 4.75 * v
