Question

1. [4 marks] Every morning, a boy scout raises a flag with a mass of 1.5 kg to the top of a 15.0 m

flagpole. How much work is done by the scout?​

Answer 1

work = force * distance

soo...

Explanation:

force = mass * gravity

(1.5 kg )*(9.8 m/
`s^(2)`) = 14.7 kgm/
`s^(2)` or Newtons

W = 14.7 N * 15 m = 220.5 Nm and since 1 N = 1 Joule

we say 220.5 Joule

220.5 J :)
