Question

This interactive involves observing the results of dropping an egg onto a surface. the size of the egg, the height from which it is dropped, and the characteristics of the landing surface can be varied. the effect of these variations upon the safety of the egg will be examined. the interactive is based on the impulse-momentum change theorem. the questions below target a interactive ability to reason scientifically.
When a small egg is dropped onto the piece of 1-inch foam, from which height did the egg
break entirely? Select all that apply.

a. When dropped from 1 meter.
b. When dropped from 5 meters.
c. When dropped from 10 meters.
d. Nonsense! The small egg never broke when dropped onto 1-inch foam.

Answer 1

Answer:

c. When dropped from 10 meters

Explanation:

Falling from a height of 10 m gives it the maximum acceleration compared to the other two heights. According to Newton's second law of motion, a force on a body is proportional to its change of momentum, this means that falling at a height of 10 m will generate more acceleration which translates to more velocity. On impact, this velocity is suddenly reduced to zero, generating a large impulse that has a higher tendency of completely shattering the egg shell.
