If you wear knee pads while skating,It will take three times as long for you to come to rest when you fall and land on your knees. how does this affect the impulse applied to your knees when you fall?

The long time will decrease the velocity which will equally decrease the impulse applied to your knee.

What is impulse?

The impulse experienced by an object is the change in momentum of the object.

J = ΔP = m(v - u)

where;

  • J is impulse
  • ΔP is change in momentum
  • m is mass of the body
  • v is final velocity
  • u is initial velocity

v = distance / time

when time of fall becomes 3 times long, the final velocity becomes 3 times smaller

Since the velocity will be reduced, the impulse applied to your knee will decrease as well.
