A fire woman dropped a person onto the safety net. Right

Answer:

m = 28.7[kg]

Explanation:

To solve this problem we must use the definition of kinetic energy, which can be calculated by means of the following equation.

$E_{k}=\frac{1}{2}*m*v^{2}\\$

where:

Ek = kinetic energy = 1800 [J]

m = mass [kg]

v = 11.2 [m/s]

$1800=\frac{1}{2}*m*(11.2)^{2}\\m = 28.7[kg]$
