A man and a child sit on a seesaw, as shown in the diagram. The seesaw consists of a plank with negligible mass resting on a fulcrum. The child is 1.25 meters from the fulcrum and the man is 0.5 meters from the fulcrum. The system is in static equilibrium. If the mass of the man is 75 kg, what must the mass of the child be? O 25 kg • 30 kg O 50 kg O 20 kg O 187.5 kg

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?
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 4 m long horizontal uniform beam of mass 24 kg is supported by a wire as shown in the figure. The wire makes an angle of 26 degrees with the beam. Attached to the beam 1.6 m from the wall is a ball with a mass of 57 kg. VWhat is the tension in the string?
The larger ball in the picture has a mass m1 = 30 kg while the smaller ball has a mass m2 = 10 kg.
