Heya user!
Here's the answer:
》Newton's second law of motion:
=> Linear momentum of a body is the product of its mass and velocity.
Examples-
•Athletes often lands on sand (or foam) after taking a high jump
> Reason: When an athlete lands from a height on a hard floor, he may hurt his feet because his feet come to rest almost instantaneously (i.e., in a very short interval of time), so a very large force is exerted by the floor on his feet. On the other hand, when he lands on sand (or foam), his feet push the sand (or foam) for some distance, therefore the time duration in which his feet come to rest, increases. As a result, the force exerted on his feet decreases and he is saved from getting hurt.
• When the glass vessels fall on a hard floor, they break, but they do not break when they fall on a carpet (or sand)
> Reason: When a glass vessel falls from a height on a hard floor, it comes to rest almost instantaneously (i.e., in a very short time) so the floor exerts a large force on the vessel and it breaks. But if it falls on a carpet (or sand), the time duration in which the vessel comes to rest, increases and so the carpet (or sand) exerts a less force on the vessel and it does not break.
