About twenty percent of the national football league weighs more than 300 pounds. at this weight, their body mass index (BMI) places them at grade 2 obesity, which is one step below morbid obesity. determine the mass of a 300 pound (1330) N football player

For a thing in free fall, so that gravity is the lone force performing on it, then the computation for weight shadows from Newton's second law.

So we will use the formula: F = ma

Where:

F is force net external

M for mass

A for acceleration

Since the force is given already, we need to solve for the mass:

F = MA

1330N = M * 9.81 m/s^2

1330N/9.81 m/s^2 = M

M = 135.57 kg or 136 kg
