Question

A person is holds a bundle of hay over his head for 30min and gets tried has he done or not. ​

Answer 1

Answer:

0

Explanation:

THE WORK DONE FORMULA

$W = F.s \: (Where \: F \: is \: Force \: s \: is \: the \: displacement \: and \: W \: is \: the \: Work \: done \: )\\ \: it \: a \: dot \: product \: hence \: it \: is \: also \: a \: scalar \: quantity$

your question have 2 possiblites  

1st(he tried and put hay on the gound )

then the total work done by man is 0 as displacement is zero

2nd (he still hold it  ) is less obvious

then work is done
