Answer:
44.068 J
Explanation:
From the question,
Work(W) = mgh............... Equation 1
Where m = mass of the book, g = acceleraton due to gravity, h = height.
Given: m = 2 kg, h = 2.3 m, g = 9.58 m/s²
Substitute these values into equation 1
W = 2×2.3×9.58
W = 44.068 J
Hence the work required to lift the book is 44.068 J
