Question

A man weighting 70kg carries a weight of 10kg to the top a tower 100m high. Calculate the work done?

Answer 1

Heya!!

We know,
$work \: done = \: force \times displacement$
now, in this case, the Man has a weight 70kg and carries an additional weight of 10 kg with him to the top if a tower 100 m high.
so, the work done by the man will be
$w = (10 + 70) \times 100 \\ w = 80 \times 100 \\ w = 8000 \: joules$
