And 60 kilograms respectively are standing on a seesaw. The seesaw is balanced when A is 2 meters from the fulcrum. How far must B be from the fulcrum in order to balance the seesaw?
To solve this problem, we can use the principle of moments. The moment of an object is the product of its mass and its distance from the fulcrum. In order for the seesaw to be balanced, the sum of the moments on one side must be equal to the sum of the moments on the other side.
Let's assume that B is x meters away from the fulcrum. The moment of A is 40 kg * 2 m = 80 kg*m. The moment of B is 50 kg * x m = 50x kg*m. The moment of C is 60 kg * (2 + x) m = 120 kg*m + 60x kg*m.
Since the seesaw is balanced, the sum of the moments on one side must be equal to the sum of the moments on the other side. Therefore, we have the equation:
80 kg*m + 50x kg*m = 120 kg*m + 60x kg*m
Simplifying this equation, we get:
80 kg*m - 120 kg*m = 60x kg*m - 50x kg*m
-40 kg*m = 10x kg*m
-4 = x
Therefore, B must be 4 meters away from the fulcrum in order to balance the seesaw.

Let's assume that B is x meters away from the fulcrum. The moment of A is 40 kg * 2 m = 80 kg*m. The moment of B is 50 kg * x m = 50x kg*m. The moment of C is 60 kg * (2 + x) m = 120 kg*m + 60x kg*m.

80 kg*m + 50x kg*m = 120 kg*m + 60x kg*m
Simplifying this equation, we get:
80 kg*m - 120 kg*m = 60x kg*m - 50x kg*m
-40 kg*m = 10x kg*m
-4 = x
Therefore, B must be 4 meters away from the fulcrum in order to balance the seesaw.
