<h3><u>Answer;</u> </h3>
= 0.03066 m
<h3><u>Explanation;</u></h3>
Work done or energy by a spring or an elastic material is given by the formula;
Potential energy = 1/2 kx²
Where, k is the spring constant and x is the distance stretched.
Therefore;
47 J = 1/2 (100000 n/m) x²
47 J = 50, 000 x²
x² = 47 /50,000
x² = 0.00094
x = 0.03066 m
Therefore,<u> x = 0.03066 m </u>
i know this is pretty late { and you probably wouldve not needed this anyway } but here you go ....
<h2>since weight is in newtons, we need to convert the kg to newton </h2><h3>the formula to convert is kg x 9.807 = N</h3>
hope that helps :))
It would take 500 seconds, because 2500 divided by 5 is 500
The line is called equator.
Answer:
At 400 m the potential energy of the mountain climber doubled the initial value.
Explanation:
Given;
initial height of the mountain climber = 200 m
final height of the mountain climber, = 400 m
The potential energy of the mountain climber is calculated as;
Potential energy, P.E = mgh
At 200 m, P.E₁ = mg x 200 = 200mg
At 400 m, P.E₂ = mg x 400 = 400mg
Then, at 400 m, P.E₂ = 2 x 200mg = 2 x P.E₁
Therefore, at 400 m the potential energy of the mountain climber doubled the initial value.
