Against the sheet, the egg did not break because the sheet applied a small force over?????????????
A
a longer time
B
a shorter time
C
a smaller area
D
a larger area
Explanation: 

Detailed explanation-1: -But in the case of sheet, the impulse force is much lower on the egg as with a sheet, the force to stop the egg is spread over a long time period. Due to this, there is no sufficient impulse to crack the shell. Conclusion: So, egg cannot break when it is thrown against the sagging sheet.

Detailed explanation-2: -It won’t break because the sheet slows the movement of the egg as it comes to a stop. The law of motion says that the faster you change the speed of an object, the greater the force applied to the object will be.

Detailed explanation-3: -Usually, it takes a little more than 5 ½ pounds of force to crack an eggshell-much less than the weight of a human being-but the precise amount of force needed depends on the direction in which that force is applied and how much the force is distributed (or not) over the surface of the shell.

Detailed explanation-4: -The egg misses the bed sheet and collides with the wall. In these unexpected cases, the collision between wall and egg lasts for a short period of time, thus maximizing the effect of the force on the egg.

Detailed explanation-5: -The egg dropped on the floor stops very quickly, which means the force on the egg is large, so it breaks. The egg dropped on the pillow slows down and stops more slowly since the pillow is squishy, therefore the force on the egg is smaller and the egg does not break.
