Three children are trying to balance on a seesaw, which includes a fulcrum rock acting as a pivot at the center, and a very light board 3.8 m long. Two playmates are already on either end. Boy A has a mass of 45 kg, and boy Ba mass of 35 kg. (Figure 1) Part A Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw? Express your answer using two significant figures. Figure < 1 of 1 m=35 kg Submit Request Answer m= 45 kg m= 25 kg Provide Feedback

A little league player balances a bat 57.0 cm from one end. She then hangs her 0.540-kg batting helmet on that end of the bat and the balance point moves 23.0 cm toward the helmet. Determine the mass of the bat. kg Additional Materials O Reading

The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb.    Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.

A 164-cm-tall person lies on a light (massless) board which is supported by two scales, one under the top of her head and one beneath the bottom of her feet. The two scales read, respectively, 35.1 and 31.6 kg. (Figure 1) Part A What distance is the center of gravity of this person from the bottom of her feet?

A rider of mass 77.0-kg sits 1.60 meters left of the pivot point.  A different rider sits 3.3 meters to the right of the pivot point. If the see-saw is in equilibrium, what is the rider on the right's mass? The mass of the see-saw is 18.9-kg  Give your answer in kilograms to 3  significant figures (1 decimal place).

Jack and Jill want to balance their seesaw. Where should they set the fulcrum? Jack has a mass of 25 kg, Jill has a mass of 15 kg, and the seesaw board has a mass of 20.0 kg.

3. A meter stick has a pivot that is located in the middle (50 cm). On this meter stick we place 150 g @ 32 cm, 300 g @ 45 cm, 100 g @80 cm and 300 g @80 cm. a. How much mass needs to be placed at 55 cm in order to balance the meter stick. b. Where will you put 500 g in order to balance the meter stick?

A rider of mass 78.0-kg sits 1.70 meters left of the pivot point. A different rider sits 3.5 meters to the right of the pivot point. If the see-saw is in equilibrium, what is the rider on the right's mass? The mass of the see-saw is 19.2-kg Give your answer in kilograms to the correct number of significant figures.
