Suppose two children are using a uniform seesaw that is 3.00 m long and has its center of mass over the pivot. The first child has a mass of 30.0 kg and sits 1.40 m from the pivot. (a) Calculate where the second 18.0 kg child must sit to balance the seesaw.
(b) What is unreasonable about the result?
(c) Which premise is unreasonable, or which premises are inconsistent?
Please show work and explanations.

The two children are balanced on a seesaw of negligible mass (this assumption is made to keep the example simple). The first child is 26.0 kg and sits .160 m to the left of the pivot. The seesaw has a mass of 12 kg. If the second child is 32.0 kg, how far is she from the pivot? What is the supporting force exerted by the pivot?

Question 2 (2 Points) Static Equilibrium - Modified Seesaw (including mass of the seesaw) The two children shown in the Figure are balanced on a seesaw. The first child has a mass of m1= 16.2 kg and sits r1 = 2.1 m from the pivot. The center of mass of the seesaw is r3 = 0.36 m to the left of the pivot (on the side of the lighter child) and assume a mass of M = 13.4 kg for...
