How does Newton's three laws of motion apply to the egg drop project
BabaBlast [244]
<span> Newtons First Law is applied on my egg experiment because it will not move or change it's acceleration until a force acts upon it. Newton's Second Law is applied because of the acceleration caused by natural forces as the egg is plummeting to the earth. And the amount of acceleration the egg has will be largely affected by the amount of force used to hurl the egg to the ground. The Third Law of Motion affects the egg because the amount of force the egg hits the ground with, the ground pushes back with equal and opposite force.</span>

antoniya [11.8K]

Explanation:

Given that, the height of the tide measured at a seaside community varies according to the number of hours t after midnight. The height is given by the equation as :

h=-\dfrac{1}{2}t^2+6t-9

When the tide first be at 6 ft, put h = 6 ft in above equation as :

-\dfrac{1}{2}t^2+6t-9=6

-t^2+12t-18=0

On solving the above equation to find the value of t. It is equal to :

t = 3.551 seconds

or

t = 8.449 seconds

So, the tide of 6 ft is at  3.551 seconds and 8.449 seconds. Hence, this is the required solution.
