What is the mass of a child if the force of gravity on the child's body is 100 N?
A. 9.8 kg
B. 4.45 kg
C. 22.5 kg
D. 10.2 kg
what?
F=m*g
F/g=m
100/9.8=10.2 kg
thank you kind sir
To determine the mass of the child, we can use the formula F = m * g, where F is the force of gravity, m is the mass, and g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth).
In this case, the force of gravity on the child's body is given as 100 N.
So, we can rearrange the formula to solve for mass (m = F/g):
mass = 100 N / 9.8 m/s^2
Calculating this, we get:
mass ≈ 10.2 kg
Therefore, the answer is D. 10.2 kg.
