The last option in Puerto Rico where it’s sunny and 88°
The energy of a system is the product of the force applied and the distance travel. It will have a units of Joules which is equal to Force - meter. So, Energy = F x d. We calculate the force as follows:
60.0 J = F x 0.330 m
F = 181.82 N
Answer: 20231.75km
Explanation: Assuming the earth is a sphere with a radius r, the formulae for calculating the distance between 2 points on the earth surface is given as
l = distance between two points on the earth surface (km)
π = 22/7
r = radius of the earth = 4000miles =6437.376 km ( we will be using kilometer because that is the SI unit for distance)
α = angle between the two cities on the earth surface. For our question, α=180 because one of the city is north and the second city is in the opposite direction <em>(due north of the first)</em>
By slotting in the parameters into the foemulae, we have that

The simple harmonic motion and Hooke's law allows to find the displacement when hanging the mass of 2 kg is:
x = 2.45 m
Simple harmonic motion is a motion where the restoring force is proportional to the displacement.
x = A cos (wt + Ф)
Where x is the displacement, A is the amplitude, w is the angular velocity, t is the time
The angular velocity is
w² = k / m
Where k is the spring constant and m is the mass.
From the graph we see that the oscillatory wave has half a period between the times t₁ = and t₂ = , therefore the period is:
T = π s.
The angle in a complete oscillation is θ = 2π rad.
The angular kinematics defines the angular velocity with the angle in the unit of time.
w =
w =
w = 2 rad / s
Let's find the spring constant.
k = w² m
Let's calculate.
k = 2² 2
k = 8 N / m
Hooke's law says that the restoring force of a spring is<em> proportional</em> to its displacement.
F = - k x
mg = - k x
x =
x =
x = 2.45 m
In conclusion using simple harmonic motion and Hooke's law we can find the displacement when hanging the 2kg mass is:
x = 2.45 m
