Answer 1

$\huge\bold{Question}$

A porter lifts a luggage of 15 kg from the ground and puts it on his head 1.5m above the ground calculate the workdone.

$\huge\bold{@nswer}$

Given =>
$\boxed{\bold{Mass\:of\:the\: luggage}}$ , m = 15 Kg.

Given =>$\boxed{\bold{Displacement}}$ ,S = 1.5 m

=>We will use the formula of work done

$\boxed{\bold{Work \:done}}$ = F × S = Mg × S.

= 15 kg × 10 ms × 1.5 m.

= 225 kg ms .

= 255 J.

Answer 2

$\huge\underline\mathrm{Question}$

A Porter lifts a luggage of 15 kg from ground and puts it on his head 1.5 m above the ground calculate the work done by him on the luggage.

$\huge\underline\mathrm{AnSweR}$

Mass of luggage,m=15 kg and

displacement=1.5m

work done, W=F×s=mg×s

ㅤㅤㅤㅤㅤㅤ=15kg×10m s²×1.5 m

ㅤㅤㅤㅤㅤㅤ=225 kg m s² m

ㅤㅤㅤㅤㅤㅤ=225 N m=225 J

Work done is 225 J.
