Question

Henry Heavyweight weighs 1400N and stands on a pair of bathroom scales so that one scale reads twice as much as the other.

What are the scale readings?

Answer 1

The answers would be 47.6 and 95.2

The solution would be like this for this specific problem:

2 W + 1 W = 3 W = 1400N
W=467N = 467N/(9.8N/kg)= 47.6 kg
2 W = 95.2kg

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

Answer 2

The scales readings are 933.3 N and 466.7 N.

Step-by-step explanation:

Given that,

Weight = 1400 N

We need to calculate the reading of scale

We know he has twice the weight on one scale and his total is 1400 N. These can be written as two simultaneous equations .

`W=scale_(1)+scale_(2)`

`1400=scale_(1)+scale_(2)`....(I)

`scale_(1)=2* scale_(2)`.....(II)

Put the value from equation (II) into equation (I)

`1400=2* scale_(2)+scale_(2)`

`1400=3 scale_(2)`

`scale_(2)=(1400)/(3)`

`scale_(2)=466.7\ N`

Now, Put the value in the equation (I)

`1400=scale_(1)+466.7`

`scale_(1)=1400-466.7`

`scale_(1)=933.3\ N`

Hence, The scales readings are 933.3 N and 466.7 N.
