B. 800 kg
C. 50 kg
D. 4802 kg
Answer:
C. 50 kg
Explanation:
Force of gravity on an object is the weight of the object and is given by mass times acceleration due to gravity. The acceleration due to gravity is the acceleration 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 newtons, i.e. F = mg which means that 490 newtons = 9.8 times mass. Therefore, mass of the child is 490 / 9.8 = 50 kg.
