What is the mass of a 210 N athlete?

To find the mass of the athlete, you can use the formula ( \text{Weight} = \text{mass} \times \text{gravity} ). Assuming standard gravity is approximately ( 9.81 , \text{m/s}^2 ), you can rearrange the formula to find mass: ( \text{mass} = \frac{\text{Weight}}{\text{gravity}} ). Thus, the mass of the athlete is ( \frac{210 , \text{N}}{9.81 , \text{m/s}^2} \approx 21.4 , \text{kg} ).
