Question

A man hold a child on his shoulder watching a football match howmuch workhas he done if the lasts for 2 hours

Answer 1

Answer:

None

Explanation:

Assuming the man or child is not moving, the man does not do any work.

W = work

F = force

d = distance

The general equation for work is:

W = F*d*cos(theta)

Since neither in the problem moved any distance, d would be 0, so W would be 0 as well.

Hope this helps!!
