Athletes jump on a bed of sand during long jump is an example of Newton's​

Answer 1

$\huge\sf\red{Required~Answer}$

Athletes jump on a bed of sand during long jump is an example of Newton's Second Law of motion or Impulse force.

• Why does the athlete jumps on the foam or sand instead of hard ground?

• The total change in momentum m(v - u) remains a constant quantity, when the Athlete jumps from a certain height. This change in momentum is numerically equal to F × t. Where,

• F is the force applied by the ground on the athlete.
• And t is the very short interval of time.

So, When the athlete jumps on foam, the time 't' increases and the force acting on the athlete by the foam decreases. The athlete doesn't comes to rest suddenly and does not get hurt.

Answer 2

• Athletes jump on a bed of sand during long jump is an example of Newton's Second Law of motion or Impulse force.
