Seesaw physics equation
WebIf two people (Person A and Person B) sit on a seesaw, the moment of each person equals their weight multiplied by their distance from the pivot. When balanced, these moments are equal. Web(II) Three children are trying to balance on a seesaw, which consists of a fulcrum rock, acting as a pivot at the center, and a very light board 3.6 $\mathrm{m}$ long $(\text { Fig. } 9-50 …

Webb. Plan “Write an equation.” c. Solve “Solve the equation and answer the problem.” (Be sure to include units.) d. Examine “Check to see if the answer makes sense.” 7. Mary Jo weighs 120 pounds and Dan weighs 160 pounds. They are seated at opposite ends of a seesaw. Dan and Mary Jo are 14 feet apart, and the seesaw is balanced. WebThis equation yields what might have been guessed at the beginning: F p = w 1 + w 2. 9.19 So, the pivot supplies a supporting force equal to the total weight of the system: F p = m 1 g + m 2 g. 9.20 Entering known values gives F p = 26.0 kg 9.80 m/s 2 + 32.0 kg 9.80 m/s 2 = 568 N. 9.21 Discussion The two results make intuitive sense.
