The weight of the girl with a mass of 40 kg is ; 392.4 N
The weight of an object represents the amount of force exerted on the object by the gravitational field and it is calculated as :
W = m*g
m ( mass ) = 40 kg
g ( acceleration due to gravity ) = 9.81 m/s²
∴ weight of the girl ( w ) = 40 * 9.81 = 392.4 N
Hence we can conclude the weight of the girl with a mass of 40 kg is
392.4 N.
