Simulationinvolves an experimentation procedure which is performed in other to build a tentative model before being replicated in the real world. Hence, an egg is similar in terms of shape but differs in terms of size and strength
Testing the strength of an helmet using a real human head to could be deadly, hence similar objects are used to build a safe helmet before being tested on humans.
Model to be chosen would have similar characteristics with the real object. Interms of shape, an egg could be used to model the shape of the human head as they are somewhat similar in that aspect.
However, when it comes to characteristics such as size, hardness or thickness, an egg does not meet these properties when compared with the human head.

Explanation: One way a chicken egg could be a good model for a human head in a bicycle helmet design experiment is that the egg has similarities to a human head in a helmet.
One way it's a bad example is that the chicken egg does not have the same thickness of human skulls or a bicycle helmet. It is just to fragile to have accurate results.

Answer:
The final velocity is -49.05 meters per second.
Explanation:
Let's use an equation of constant acceleration:
Where a is the acceleration and g is the acceleration caused by gravity.
Since the object is being dropped from rest, .
We're looking for the speed after 5 seconds, so .
So the final velocity is -49.05 meters per second.
The height of the steel beam is 30.9 m
Explanation:
The gravitational potential energy of an object is the energy possessed by an object due to its position in the gravitational field. Near the Earth's surface, the gravitational potential energy of an object is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object above the ground
For the steel beam in this problem, we have:
U = 100,000 J is the potential energy
m = 330 kg is the mass
Solving for h, we find the height of the steel beam:
