QUESTION 3 Why does an egg break if it is dropped from 1 meter onto hardened concrete but does not break if it is dropped from 1 me onto a soft mattress? O The mattress increases the inertia of the egg and makes it more resistant to change so it doesn't break. O The mattress' cushioning increases the contact time with the egg and decreases the force acting on the egg. O The mattress' cushioning decreases the contact time with the egg and decreases the force acting on the egg. O None of these
