A boy and a girl are balanced on a massless seesaw. The boy has a mass of 60 kg and the girl's mass is 50 kg. If the boy sits 1.5 m from the pivot point on one side of the seesaw, where must the girl sit on the other side for equilibrium? 8 m B) 1.3 m C) 2.5 m D) 3.0 m
Can you draw a free-body diagram of this problem? 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 3.2 m long as shown in the figure. Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw?
Two children are playing on a seesaw trying to balance. If the child on the left sits 2 meters away from the fulcrum and weighs 40 kg, and the child on the right weighs 32 kg, how far away from the pivot point will the child on the right have to sit? A. 2.5 m B. 3 m C. 1.5 m D. 2.75 m
Three children are playing on a seesaw. The largest child has a mass of 50 kg and sits on the right side of the seesaw 0.9 m from the fulcrum. The middle child has a mass of 40 kg and sits on the left side of the seesaw 2.5 m from the fulcrum. Where does the smallest child, who has a mass of 25 kg, need to sit in order to balance the seesaw?
The larger ball in the picture has a mass m1 = 30 kg while the smaller ball has a mass m2 = 10 kg. (a) If the larger ball is placed 1 m away from the fulcrum, how far away from the fulcrum must the smaller ball be placed in order for the seesaw to be in equilibrium? Here the fulcrum is in the middle of the seesaw. (b) Now the fulcrum is located one fourth of the way from the left end of the plank and the balls are placed at either end. If the larger ball has the same mass as in part (a), what must the mass of the smaller ball be in order for the seesaw to be in equilibrium? Ignore the mass of the plank.
A student plays on a see-saw with her father. The student has a weight of 250 N and is seated 2.4 m from the axis of rotation. Her father balances her when he is seated 0.8 m from the axis. The father's weight is 725 N. 500 N. 750 N. 667 N. 250 N.
A 198 kg, 5 m long beam sits on top of two posts. A 3 kg pail sits 0.7 m from the left edge of the beam. Can the 62 kg boy get to the right end of the beam without it falling over? If not, how close to the edge can he get?
Luc, who is 1.80 m tall and weighs 950 N, is standing at the center of a playground merry-go-round with his arms extended, holding a 4.0 kg dumbbell in each hand. The merry-go-round can be modeled as a 4.0-m-diameter disk with a weight of 1500 N. Luc's body can be modeled as a uniform 40-cm-diameter cylinder with massless arms extending to hands that are 85 cm from his center. The merry-go-round is coasting at a steady 35 rpm when Luc brings his hands in to his chest. Afterward, what is the angular velocity, in rpm, of the merry-go-round?
