What is the momentum of a 100 kg football player?
Q: A football player has a mass of 100kg and is running 10m/s. What is his momentum? A: 100kg x 10m/s= 1000kg⋅m/s Page 8 Practice 1 1. Read this article on momentum.
What is the velocity of an object that has a mass of 2.5 kg and a momentum of 1000 kg m s?
400 m/s
When a dish falls will the change in momentum be less if it lands on a carpet than if it lands on a hard floor careful !)?
Explain your answer to your neighbor. When a dish falls, will the change in momentum be less if it lands on a carpet than if it lands on a hard floor? (Careful!) Explanation: The momentum becomes zero in both cases, so both changes are the same.
Why does an object at rest have no momentum?
Objects at rest do not have momentum – they do not have any “mass in motion.” Both variables – mass and velocity – are important in comparing the momentum of two objects. The momentum equation can help us to think about how a change in one of the two variables might affect the momentum of an object.
Why does an egg break when thrown against a brick wall but not against a bed sheet?
When an egg is thrown against a brick wall, it has little time to decelerate, so it breaks on contact. But if an egg is thrown at a hanging sheet, the momentum decreases over a longer amount of time and the force is smaller. This is why an egg breaks when thrown at a wall, but not when thrown at a sheet.
Can you throw a raw egg into a sagging sheet without breaking it?
If you throw a raw egg against a wall, you’ll break it. But when Peter Hopkinson throws an egg at the same speed into a sagging sheet, it doesn’t break. When thrown against a wall this impulse force acts against the egg all at the same time, which caused it to shatter.
How do you drop an egg on concrete without cracking it?
Check the answer to the Riddle! The correct answer to the Riddle is “Concrete floor can not be cracked by an egg”.
What material can protect an egg from breaking?
Possibilities include balloons, popcorn, packing peanuts, wads of paper or cereal puffs. Encase the egg in any of these inside a paper or plastic bag, a sock or a stocking. If you have any bubble wrap around the house, wrapping the egg in several layers of bubble wrap should also provide a good cushion.
