Refer to the diagram shown below.

The basket is represented by a weightless rigid beam of length 0.78 m.
The x-coordinate is measured from the left end of the basket.

The mass at x=0 is 2*0.55 = 1.1 kg.
The weight acting at x = 0 is W₁ = 1.1*9.8 = 10.78 N

The mass near the right end is 1.8 kg.
Its weight is W₂ = 1.8*9.8 = 17.64 N

The fulcrum is in the middle of the basket, therefore its location is
x = 0.78/2 = 0.39 m.

For equilibrium, the sum of moments about the fulcrum is zero.
Therefore
(10.78 N)*(0.39 m) - (17.64 N)*(x-0.39 m) = 0
4.2042 - 17.64x + 6.8796 = 0
-17.64x = -11.0838
x = 0.6283 m

Answer:  0.63 m from the left end.

  1. High/low notes have high/low frequency, not high/low amplitude.
  2. Heartz measures the number of waves per second, not per hour.
  3. Sounds do not travel in space because it's empty
  4. Sounds make our eardrum vibrate. The diaphragm is the muscle we use to breathe.
  5. Soft, pale materials are best for sound proofing because they absorb the waves.
  6. In the next paragraph, ultrasound and infrasound are inverted (ultra means "over, above" and infra means "below").
