Question

The mass of a body is hundred kilogram calculate the amount of work done by the body in climbing 20 metre high building gravitational 9.8 metre per square

Answer 1

Force = mass ×g

=100*9.8= 980

Work done =F*s

W= 980*20

= 19600J

Answer 2

Explanation:

$αɳรωεɾ⤵$

ƒσɾcε = ɱαรร × ɠ

= 100*9.8 = 980

ωσɾҡ ∂σɳε = ƒ*ร

ω = 980*20

= 19600ʝ
