U = potential energy of a spring at a certain position
k = the spring constant, specific to the spring, with units N/m.
x = distance the spring is stretched or compressed away from equilibrium
Potential Energy: Elastic Formula Questions:
1) A spring, which has a spring constant k = 7.50 N/m, has been stretched 0.40 m from its equilibrium position. What is the potential energy now stored in the spring?
Answer: The spring has been stretched x = 0.40 m from equilibrium. The potential energy can be found using the formula:
U = 1/2kx2
U = 1/2(7.50 N/m)(0.40 m)2
U = 0.60 N∙m
U = 0.60 J
Answer:
Janet age 5 years ago is 19-5= 14 years
Step-by-step explanation:
janet is now 25 years younger than her mother Carol.
Let x be the age of mother
Janet is x-25
In 6 years, Carol becomes x+6

Solve for x

multiply both sides by 2

subtract x on both sides

add 38 on both sides
x=44
Age of Carol now = 44
Age of Janet now = 44-25=19 years
Janet age 5 years ago is 19-5= 14 years

Answer:
We kindly ask you to see the explanation and the image attached below for further details.
Step-by-step explanation:
From Function Theory we know that third order polynomials are continuous functions with one relative minimum and one relative maximum and whose domain and range comprehends the set of all real numbers. Since the leading coefficient of the polynomial is positive, then two increasing intervals and only one increasing interval exist.
Now we proceed to graph the function and label each relevant information when possible.
