A man with a weight of 550 N climbs a ladder to a height of 3.5m. How much work did he do?

1925 joules

Explanation:

weight of man = 550 N

height climbed = 3.5m

Work = ?

Since, work is done when the man pulled his weight over the height; work is expressed as the product of weight and height climbed

i.e Workdone = 550N x 3.5m

= 1925 joules

Thus, the man did a work of 1925 joules while climbing

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
