Free runners jump long distances and land on the ground or a wall. How do they apply Newton’s second law to lessen the force of impact?

Respuesta :

As we know that as per Newton's II law we have

[tex]F = \frac{dP}{dt}[/tex]

here we will have

[tex]dP [/tex] = change in momentum

[tex]dt[/tex] = time interval in which momentum is changed

now in order to have least injury during jumping we need to have least force on the jumper

so in order to have least force we can say that the momentum must have to change in maximum time so that amount of force must be least

So we need to increase the time in which momentum of the system is changed
