Answer:

I. Weight = 490 Newton

II. Newton's Second Law of Motion

III. Force = 100 Newton

Explanation:

Given the following data;

Mass = 50 kg

Acceleration = 2 m/s²

I. To find the weight of the gymnast;

Weight = mass * acceleration due to gravity

We know that acceleration due to gravity is equal to 9.8 m/s².

Weight = 50 * 9.8

Weight = 490 Newton

II. Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

[tex] F = ma[/tex]

III. To find the force, we would use the following formula;

[tex] F = ma [/tex]

[tex] F = 50 * 2[/tex]

Force = 100 Newton
