Question

What is the amount of work needed to lift a book weighing 20.0n a distance of 2.0m

Answer 1

Answer: 40J (Joules)
Explanation below:
Work = Force x Distance
Answer = 20N x 2m
20x2=40
Answer: 40 Joules

Answer 2

w = 40 Joules

Step-by-step explanation:

Formula to get work:

W = F × S

where:

w = work/Joules

F = force/newtons

s = displacement/meters

substitute:

w = 20 × 2

w = 40J
