$\overrightarrow{F} \Delta t = m \Delta \overrightarrow{v}$

Vedclass · Answer

(C) The correct relation is $\overrightarrow{F} \Delta t = m \Delta \overrightarrow{v}$,which represents the impulse-momentum theorem.From this,we can write $F = \frac{m \Delta \overrightarrow{v}}{\Delta t}$.When you bend your knees upon landing,the time interval $\Delta t$ during which your velocity changes to zero increases.Since the change in momentum $m \Delta \overrightarrow{v}$ is constant,increasing the time $\Delta t$ results in a decrease in the impulsive force $F$ exerted on your knees,thereby reducing the risk of injury.

Consider the following statement: When jumping from some height,you should bend your knees as you come to rest,instead of keeping your legs stiff. Which of the following relations can be useful in explaining the statement?
