To Find :-

  • The work done by a man.

Solution :-

  • Mass (m) = 75 kg

  • Total height gained (h) = 10 × 10 cm → 100 cm → 1 m

  • Acceleration due to gravity (g) = 10 m/s²

Now,

Work done by a man,

\red\bigstar W = mgh

Where,

  • W → Work done by a man
  • m → Mass of a man
  • g → Acceleration due to gravity
  • h → height of a man

[ Put the values ]

\longrightarrow W = 75 × 10 × 1

\longrightarrow W = 75 × 10

\longrightarrow W = 750 joule \green\bigstar

Therefore,

The work done by a man is 750 J.

Explanation:

Given:-

Mass=75kg

Total height gained =10×10=100cm=1m

G=10m/s^2

To find:-

The work done by the man=W

Solution:-

As we know that

{:}\longrightarrow {\boxed{W=mgh}}

{:}\longrightarrow W=75×10×1

{:}\longrightarrow 75×10

{:}\longrightarrow 750Joule

{:}\longrightarrow {\underline{\boxed {\bf {W=750J}}}}
