Question

Rita weighing 36 kg climbs up a ladder of
15 m height. What is the work done by her
against the force of gravity? Given that
g = 10 m/s?​

Answer 1

Given -

• Mass = 36 kg

• Height = 15 m

• Acceleration due to gravity = 10 m/s²

To find -

• Work done.

Solution -

Formula to calculate work done when mass, height and gravity is given.

• ⇛ Work = Mass × Gravity × Height

Substitute the given values.

⇛ 36 × 15 × 10

⇛ 5400 J

$\large{\underline{\boxed{\sf{\green{Work~done= 5400~J}}}}}$
