# Jumping clowns

A clown of mass $$100~\mbox{kg}$$ jumps from a height of $$2~\mbox{m}$$ onto one end of a seesaw, which is above the ground (see figure). On the other end of the seesaw, which is on the ground, is a $$70~\mbox{kg}$$ clown who is launched into the air vertically upwards. If $$2/3$$ of the total energy of the first clown is transferred to the second, how high in the air does the second clown go in meters?
