- 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 3.4 m long (Figure 1). Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. ▼ Part A Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw? Express your answer to two significant figures and include the appropriate units. for Part A for Part Addo for Part redo for Part A reset for Part A keyboard shortcuts for Part A help for Part A x= Value UnitsA 1.5 kg block is connected by a rope across a 50-cm-diameter, 2.0 kg pulley, as shown. There is no friction in the axle, but there is friction between the rope and the pulley; the rope doesn’t slip. The weight is accelerating upward at 1.2 m/s2. What is the tension in the rope on the right side of the pulley?A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 6.35 g coins stacked over the 11.5 cm mark, the stick is found to balance at the 43.4 cm mark. What is the mass of the meter stick?
- A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 6.21 g coins stacked over the 24.9 cm mark, the stick is found to balance at the 36.4 cm mark. What is the mass of the meter stick?Two children are trying to balance on a seesaw, which includes a fulcrum and a board that is 10m long. Boy A has a mass of 50kg, and boy B has a mass of 35kg. How far from the pivot point should boy B be to maintain stable equilibrium?Suppose we place a 9.6-g weight at the 10-cm mark on a uniform meter stick, and we find that the meter stick now balances at the 45-cm mark. What is the mass of the meter stick
- B4A 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.
- Three children are trying to balance on a seesaw. The seesaw is 4.1 m long and pivots about a rock at its center. Louie and Laura are already sitting on opposite ends. If Martha weighs 33 kg, where should she sit so as to balance the seesaw?A rider of mass 78.0-kg sits 1.70 meters left of the pivot point.
