Student’s Response was:
When trying to catch an egg with the furthest distance, there are several things to keep in mind. Things such as the weight of the egg, the distance you are throwing it, and how you catch the egg can change the results greatly.
First off, when throwing something as small as an egg, one must keep in mind that the further the distance, the more force is exerted into throwing the egg. With more force exerted into the egg, the more momentum there will be. This is especially important when catching the egg, because catching it the wrong way can result in it breaking.
The catching of the egg can be particularly difficult, because the egg is very brittle and fragile. In order to reduce the momentum, you must grab the egg by its sides so it does not splatter on your hand. The egg’s impulse which is it’s average force over a period of time, must be reduced in order to ensure a safe landing for the egg. By grabbing the egg by the sides, you are reducing it’s momentum and impulse to later make the egg fall into your palm.
Tutor’s response was: To win the competition, we need to throw the egg as high as we can. So when it fall down, it will have a high velocity as well. Mass of the egg is fixed. So if we need to win this competition, we should be prepared to face a high momentum that we will receive when it come down. Lets say that we take time “t” to catch this egg. So the force while catching the egg will be “F” given by:
So F= m(vf-vi)/t
And we have already seen that mass m is fixed.
Also Vf =0 because the egg finally comes to rest after catching.
Vi is the velocity which was there just before catching the egg and we have…[ad_2]
