What’s the question though
According to the definition of the force, It is defined as <u>the multiplication of the mass and acceleration</u> (or, the rate change of the quantity of motion)
where:
- F: is the force in Newtons (N)
- m: is the mass in kilograms (Kg)
- a: is the acceleration in
Then, in our problem
Force of gravity on an object is the weight of the object and is given by mass times accerelation due to gravity. The accerelation due to gravity is the accerelation of an object in free fall and is given by 9.8m/s^2. Given that the force of gravity acting on a child's mass on earth is 490 newtns, i.e. F = mg which means that 490 newtons = 9.8 times mass. Therefore, mass of the child is 490 / 9.8 = 50 kg.
Mostly gravity voloume and sometimes what it is made of
