The mass of a child is 20 kg. What is the weight of the child if the acceleration due to gravity is taken as [tex]9.8 \, \text{m/s}^2[/tex]?

A. 196 N
B. 220 N
C. 190 N
D. 210 N

Answer :

Final answer:

The weight of the child is 196 N.

Explanation:

The weight of an object can be calculated using the equation w = mg, where w is the weight, m is the mass, and g is the acceleration due to gravity. In this case, the mass of the child is given as 20 kg and the acceleration due to gravity is 9.8 m/s². Thus, the weight of the child would be:

w = (20 kg) * (9.8 m/s²) = 196 N
