Question

What is work done in holding a 50 kg suitcase while waiting for a bus for 50 minutes

Answer 1

Answer:

0 joules

Explanation

work done is 0J because there is no displacement of object in any direction.

Answer 2

Answer:-

Given:-

m = 50kg.

T =50 minutes

Explanation:-

$W=F.S cos \alpha$

as man is standing so,

$\alpha = 90 \: degrees$

and the displacement is zero.

substituting the value in the work done formula

$W=F.S cos(90)$

cos(90) =0. and displacement =0.

$W = 0$

so,work done in holding the suitcase is zero. i.e.

$W = 0$
