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

Answer: 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
