Question

calculate the work done by a girl weighing 55 kg is climbing up a hill 1500 m high g =9.8 m\s ​

Answer 1

${\huge{\underline{\red{Answer:}}}}$

W = 808.5 KJ

${\huge{\underline{\blue{Given:}}}}$

mass (m) = 55 kg

distance (S) = 1500 m

acceleration due to gravity (g) = 9.8 m/s²

${\huge{\underline{\pink{To Find:}}}}$

Work done by the girl

${\huge{\underline{\orange{Formulas:}}}}$

W = F × S ; F = ma

${\huge{\underline{\green{Solution:}}}}$

W = FS = mg × S

= 55 × 9.8 × 1500

= 8,08,500 J = 808.5 KJ

Answer 2

808.5 KJ
