-- We're pretty sure that this question is based on an assumption of EARTH, so we know that we're dealing with a sphere of roughly 3.950 miles radius.

-- The distance on the sphere between 30° west and 60° east is 90° of longitude.  That's 1/4 of the total circumference of the circle.  

-- BUT ..... Way up here at 60° N latitude, the circle is not as big as the equator.  It's radius/diameter/circumference is only cos(60°) = 0.5 of the Earth's total.

-- So the length of our quarter-circle arc is about

(1/4) x (2 · π · 3,950 miles) x (0.5) =

(1/4) x (3,950 π miles) =

988 π miles = 3,104 miles

A well is being dug. A 4.5-kg bucket is filled with 28.0 kg of dirt and pulled vertically upward at a constant speed through a d
andreyandreev [35.5K]

The work done on the filled bucket in raising out of the hole is 2, 925 Joules

<h3>How to determine the work done</h3>

Using the formula:

Work done = force * distance

Note that force = mass * acceleration

F = mg + ma

F = 4. 5 * 10 + 28 * 10

F = 45 + 280

F = 325 Newton

Distance = 9m

Substitute into formula

Work done = 325 * 9

Work done = 2, 925 Joules

Therefore, the work done is 2, 925 Joules
