m = 50 kilograms – the weight of a boy standing on the floor.
It is required to determine P (Newton) – the boy’s weight.
To determine the weight of a boy, you must use the following formula:
m = P / g (where g = 9.8 Newton / kilogram), from here we find that:
P = m * g;
P = 50 * 9.8 = 490 Newton.
Answer: the weight of a boy standing on the floor weighing 50 kilograms is 490 Newtons.
