There is a seesaw. On one side sits a child (25kg) and on the other, 2.2m away, an adult (75kg).  1. Draw a diagram of this situation and label it to show the forces exerted on the seesaw by the child and adult and label the distances. 2. Write down an expression for the torques exerted about the pivot of the seesaw. 3. Where should the adult sit for the seesaw to be balanced?
