dont know what im doing wrong
Suppose a 28.4-kg child sits 0.67 m to the left of center on the same seesaw as the problem you just solved in the PRACTICE IT section. A second child sits at the end on the opposite side, and the system is balanced. (a) Find the mass of the second child. 8.55 kg (b) Find the normal force acting at the pivot point. 362 Your answers to part (a) and (b) are not consistent....

At the local playground, a 21-kg child sits on the right end of a horizontal teeter-totter, 1.8 m from the pivot point. On the left side of the pivot an adult pushes straight down on the teeter-totter with a force of 151 N. Part A In which direction does the teeter-totter rotate if the adult applies the force at a distance of 3.0 m from the pivot? (clockwise/ counterclockwise) Part B In which direction does the teeter-totter rotate if the...

Two children are sitting on opposite ends of a scesaw of negligible mass. If 40 kg child is 2.0 m from the pivoted point, how far from the pivot point will the other 30 kg child sit on the seesaw to be at equilibrium? (draw diagram to show vectors) A uniform 2000 kg beam 10 m long supports a 500 kg weight 3 meters from the right support. Calculate the forces on each of the vertical support columns? (draw diagram...
