Question

a horizontal force of 20 N moves a 10 kg block a distance of 400 cm. The work done is?

Answer 1

Explanation:

100cm = 1m

400cm = 4m

Work done = F × S

= 20×4

. = 80J

Answer 2

Answer- The work done is $80$Joule.

Explanation - Horizontal force of $20N$ moves a $10kg$ block a distance of $400cm.$

Find the work done

Solution- According to the question

Formula applied

$v=F\times s$

$=20\times \frac{400}{100}$

$=20\times 4=80Joules.$

Hence the work done is 80 Joules.
