A man weighing 70kg carries a weight of 10kg on the top of a tower 100 m high. Calculate the work done by the man. `(g = 10m//s^2)`

Text Solution

Verified by Experts

Here, force exerted by the man, `F = (70 +10)kg wt = 80kg wt`
`=80xx10N =800N (1 kg wt = 10N)`
vertical displacement,s =100 m
Work done by the man, i.e., W = `F xxs = (800 N) (100m) = 80000J `
