Answer

Breve explicación:

Según el principio de impulso - momento lineal, $J = F \Delta t=\Delta p$. Cuando un gimnasta cae, el cambio en momento lineal $\Delta p$ es fijo. Al caer sobre una manta acolchada, el intervalo de tiempo $\Delta t$ aumenta. Dado que $F=\frac{\Delta p}{\Delta t}$, un aumento en $\Delta t$ con $\Delta p$ constante implica una disminución en la fuerza $F$ que el gimnasta experimenta al chocar con el suelo.

Respuesta:

B. a mat decreases the force by increasing the time interval
