Question

A boy climbs on a pole of height 5 m. In doing so, he does 5000 J of work. Find his mass. ​

Answer 1

Answer:

MASS= WORK/HEIGHT

5000/5=1000 KG IS THE ANSWER

Answer 2

$\red\bigstar$Given That :

$\twoheadrightarrow$Heights of Pole (H) = 5m

$\twoheadrightarrow$Work Done by boy (w) = 5000J

$\twoheadrightarrow$Value of (g) = 10

$\green\bigstar$Need to Find :

$\dashrightarrow$We have to calculate Boy mass ?

$\rule{300}1$

$\blue\bigstar$Formula Used Here :

• $\dashrightarrow$w = mgh

$\pink\maltese$Where :

• $\leadsto$w = Work done
• $\leadsto$m = Mass
• $\leadsto$g = Acceleration
• $\leadsto$h = Height

$\rule{300}1$

$\orange\clubsuit$Putting Value in Formula :

$:\implies$ w = mgh

$:\implies$ 5000J = m × 10 × 5

$:\implies$ 5000J = 50m

$:\implies$ m = 5000 / 50

$:\implies$$\boxed{\underline{\pink{\mathfrak{m = 100kg}}}}$

$\rule{300}1$

$\purple\maltese$Therefore :

• ${\red{\underline{ \boxed{ \sf \pmb{ The\; Mass\; of\; Boy \;will \;be\; 100kg}}}}} \green \bigstar$
