Question

a child stands with each foot on a different scale. The left scale reads 200N and the right scale reads 150N. what is her mass in kg?

Answer 1

Answer:

35.7 kg

Explanation:

We are given that

Left scale reads =200N

Right scale reads=150 N

We have to find the mass in kg.

We know that

Weight  of child= Sum of two scales=200+150=350 N

Acceleration due to gravity=$9.8 m/s^2$

We know that

Weight= mg

Using the formula

$350=9.8 m$

$m=\frac{350}{9.8}=35.7 kg$

Hence, the mass of child=35.7 kg
